We demonstrate and compare two different photonic-based signal sources for generating the carrier wave in a wireless communication link operating in the millimeter-wave range. The first signal source uses the optical heterodyne technique to generate a 113 GHz carrier wave frequency, while the second employs a different technique based on a pulsed mode-locked source with 100 GHz repetition rate frequency. The two optical sources were fabricated in a multi-project wafer run from an active/passive generic integration platform process using standardized building blocks, including multimode interference reflectors which allow us to define the structures on chip, without the need for cleaved facet mirrors. We highlight the superior performance of the mode-locked sources over an optical heterodyne technique. Error-free transmission was achieved in this experiment. © 2016 Optical Society of America.

A record low-repetition rate from an on-chip monolithic InP extended cavity colliding-pulse mode-locked laser is experimentally reported. The device, fabricated in generic InP-based active-passive integration technology, makes use of integrated mirrors to enable its use as a building block within a photonic integrated circuit. This structure allows us to generate an electrical frequency comb with mode spacing of 1 GHz, determined by the 40.5 mm long resonator. Passive and hybrid mode-locking regime conditions are experimentally demonstrated. In the passive regime, an electrical beat tone at the fundamental repetition rate with an electrical linewidth (LW) of 398 kHz and a signal-to-noise ratio (SNR) >30 dB is measured. In the hybrid regime, the optical comb is locked to a continuous wave signal source, improving the LW of the generated signal and the SNR > 40 dB. © 2017 Optical Society of America

In the mid-infrared (Mid-IR), arrays of distributed feedback Quantum Cascade Lasers (QCL) have been developed as a serious alternative to obtain extended wavelength operation range of laser-based gas sensing systems. In order to benefit from this extended wavelength range in a single output beam we have developed a platform for InP-based photonics. After the validation of all required building blocks, we are tackling the integration into a single monolithic device. We present the design, fabrication and performances of a tunable source, fully monolithic based on the echelle grating approach. The evanescent coupler has been designed to transfer all light adiabatically from the active region to a low loss passive waveguide, while taking advantage of the high gain available in the quantum wells. These results show the first realization of a monolithic widely tunable source in the Mid-IR and would therefore benefit to the development of fully integrated spectroscopic sensor systems. © OSA 2016.

A time-domain solver for the response of a Semiconductor Optical Amplifier (SOA) relying on multigrid numerical techniques and a wideband steady state material gain coefficient is presented for the first time. Multigrid techniques enable the efficient solution of implicit time discretization schemes for the associated system of coupled differential equations, namely the carrier rate equation in the time domain and the signal amplification in the spatial domain, which in turn enable accuracy- instead of stability-restricted time-discretization of the signals. This allows lifting off the limitations of an equidistant spatio-temporal grid for the representation of the incoming signals adopted by traditional explicit SOA models, releasing an adaptive stepsize controlled solver for the dynamic SOA response with dense timesampling under a rapidly varying SOA signal output and scarce time-sampling when negligible changes are observed. © 2014 SPIE.


Home > Press > Leti and Partners in Silicon Photonics Supply-Chain Project Announce Developments on Three Mature Platforms: PLAT4M Project Focused on Speeding Industrialization of the Technology Abstract: CEA-Leti and its partners in the European FP7 project PLAT4M today announced they have built three silicon photonics platforms. The four-year project, which launched in 2013, aims at building a European-based supply chain in silicon photonics and speeding industrialization of the technology. PLAT4M, which is funded by a European Commission grant of 10.2 million euros, includes 15 leading European R&D institutes and CMOS companies, key industrial and research organizations in design and packaging, as well as end users in different application fields, to build the complete supply chain. Midway through the project, the consortium has developed advanced technologies and tools by building a coherent design flow, demonstrating manufacturability of elementary devices and process integration, and developing a packaging toolkit. The supply chain is based on technology platforms of Leti, imec and STMicroelectronics, supported by a unified design environment. The high level of maturity of the technology offered by these platforms makes them readily accessible to a broad circle of users in a fabless model. Imec’s silicon photonics platform, based on 200mm substrates, has matured thanks to the PLAT4M project. The platform is based on SOI substrates with 220nm crystalline silicon on a 2,000nm buried oxide. During this project the existing fabrication processes and integration flow have been fine tuned to have stable and repeatable performance for all photonics building blocks (couplers, waveguides, phase shifters, photodetectors). This feeds the process design kit’s robust performance specifications and guarantees quality and first-time-right designs for the platform’s fabless users for high data-rate telecom and non-telecom applications. PLAT4M partners Thales, Polytec and TNO already are using the technology. Beyond the 200mm platform, imec has pushed the limits of silicon photonics, exploiting advanced optical lithography with its 193nm immersion lithography scanner. It also has demonstrated very low propagation loss (~0.6dB/cm) for fully etched waveguides with excellent within-wafer linewidth control (standard deviation Using the imec platform, Thales demonstrated a coherent combination of laser beams (CBC). Ultimately, this application aims at producing high-power, high-energy laser sources for sensing, industry or fundamental physics. The CBC rationale is to push the limits of single laser emitters (typically fiber amplifiers) by using a large number of amplifiers and coherently adding the output beams. The coherent addition requires locking the phase of all the amplifying channels. With the number of channels, potentially very large (from tens to thousands), an integrated technology is a major concern in terms of possible industrial products. The first generation CBC demonstrator of PLAT4M, which was packaged by Tyndall UCC, included a one-to-16 channel splitter tree, plus 16 independent thermal phase modulators. The CBC experiment showed the successful coherent addition of 16 laser beams at 1.55µm. Leti has developed a new photonic platform based on 200mm SOI wafers. This process offers multilevel silicon patterning that allows the design of various passive and active devices (e.g. modulator and photodiode) with thermal tuning capability. Two AlCu levels are available for routing. A process design kit (PDK) is available for circuit design and an MPW service will be proposed in 2016. State-of-the-art performances have been demonstrated: insertion losses are below 2dB/cm for monomode waveguide and below 0.2dB/cm for multimode devices. Germanium photodiode responsivity is > 0.75A/W for a bandwidth >30GHz. Mach-Zehnder modulator VpLp is in the 2V.cm range for 2V operation with an E/O bandwidth > 25GHz. Moreover, Leti and III-V Lab have developed integrated hybrid III-V lasers and electro-absorption modulators (EAM) on silicon using a wafer-bonding technique. The hybrid lasers operate in the single-mode regime and the EAMs exhibit an extinction ratio higher than 20 dB with a drive voltage lower than 2V. Clear eye diagram has been achieved at a bit-rate of 25 Gb/s, confirming strong potential for telecom applications. During the project, ST developed an additional silicon-photonic platform in 300mm technology to be used as an R&D tool for proof-of-concept purposes. The technology, called DAPHNE (Datacom Advanced PHotonic Nanoscale Environment), is designed for evaluating new devices and subsystems for demonstration. DAPHNE is a flexible platform that perfectly fits R&D needs. While developing it, ST demonstrated wavelength-division-multiplexing solutions using arrayed waveguide gratings, echelle gratings, cascaded Mach-Zehnder interferometers and side-coupled integrated spaced sequence of resonators. Some of the configurations are designed for the 100GBase-LR4 standard, and the experimental characterization results show insertion losses below 0.5dB and channel cross-talks above 25dB for a band flatness of 2nm. Furthermore, proper operation of receiver-and-transmitter blocks to be interfaced to optical devices above them has been demonstrated at 28Gbps, making use of 65nm-node technologies. The PLAT4M WP2 work has led to a qualitative leap of the design flow for silicon photonics, allowing the photonics community to design more complex and more robust circuits. The electronics OpenAccess standard for data sharing between design-automation tools includes an extension for silicon photonics in a beta phase today. Simulation capabilities were leveraged thanks to an extensive characterization effort from the three partner fabs and thanks to the statistical data gathered for variability prediction. Paris-Sud University has studied theoretically the behavior of different phase shifters and photodetectors for a time-efficient and precise modeling. Mentor Graphics and PhoeniX Software partners have improved phase-aware routing and tool interoperability. Verification and manufacturability have reached industry-requirement standards thanks to the development of new techniques based upon the Mentor Graphics® Calibre® platform that delivers layout-versus-schematic comparison (Calibre nmLVS™), photonic rule checks (PRC) and curvilinear-aware design-rule checks (Calibre nmDRC™). Mask preparation is also improving with better pattern-density control and mask correction. About PLAT4M Consortium Members Coordinated by Leti, the consortium consists of renowned technology providers, research institutes, end users and SMEs with excellent track records in advanced photonics technologies. At the design and process level, Leti and imec have been the most prominent European players in silicon photonics for a decade. Together with University of Paris-Sud, III-V Lab and TNO, they have demonstrated numerous scientific and technological breakthroughs. For building a complete design flow, Mentor Graphics, PhoeniX BV and Si2 are world leaders in EDA tools and work together to develop a common reference platform. STMicroelectronics (France and Italy) brings its vast experience in microelectronics, and it has been engaged for the past year in the development of silicon photonics at the industrial level. Tyndall-UCC and Aifotec are renowned experts in the field of optoelectronic packaging and work together on the implementation of packaging technologies developed within PLAT4M in a manufacturing environment. End-users like Polytec and Thales Research & Technology are driving the demonstrators’ development and assessing the use of silicon photonics in their applications fields.

Whispering gallery modes supported by open circular dielectric cavities are embedded into a nonparametric two-dimensional frequency domain hybrid coupled mode theory framework. Regular aggregates of these cavities, including straight access channels, are investigated. The model enables convenient studies of the guided wave scattering process, the response of the circuit to guided wave excitation. Transmission resonances can be characterized directly in terms of resonance frequency and linewidth by computing supermodes of the entire composite circuits, comprising both cavities and bus waveguides. Examples of single ring and disk filters, a coupled-resonator optical waveguide, and a three-cavity photonic molecule in a reflector configuration allow the approach to be assessed. © 2013 Optical Society of America.

A novel type of integrated optical sensor has been evaluated theoretically. The sensing is based on the large effect of the refractive index of the measurand (generally a liquid) to the mode profile of a guided mode close to the cut-off. A special type turns over into a leaky mode-based sensor. The sensor has small size and is simple to fabricate. For the SiON technology-based structures used as a vehicle for the evaluation, a resolution of the refractive index in the range of 10-6 RIU has been achieved; however, with an operation range around a certain working index of ≈2 × 10-4 RIU only. This working index can be shifted to any desired value, within a certain range, by appropriately choosing the geometrical and material parameters. Because of technological tolerances, for practical operation, read-out based on wavelength scanning is required. The sensor can be used especially as an alarming sensor. © 2014 Elsevier B.V.

This paper describes a simulation method for 2D frequency domain scattering problems in photonics. The technique reduces the spatial dimensionality of the problem by means of global, continuous mode expansion combined with a variational formalism; the resulting equations are solved using a finite element method. Transparent influx boundary conditions and perfectly matched layers are employed at the computational window boundaries. Numerical examples validate the method. © 2010 IOP Publishing Ltd.
