The QUATERNIAN project will use quantum-dot laser technology to expand the product ranges and support the competitive position of European SMEs selling into optical access network markets. Access networks based on optical technologies are rapidly growing, as traditional copper based networking proves overly complex, energy inefficient and has high maintenance cost. With the advent of high-speed mobile computing devices, broadband connectivity is required both through fixed connections at the premises and through wireless connections. The latter requirement is often not provided by carrier networks as deep building penetration is incompatible with wide area cell networks. The QUATERNIAN project will advance the position of SMEs supplying equipment both for rapidly growing high-speed wired optical access networks and high-speed radio-over-fibre (RoF) building access networks. Quantum Dot laser materials grown on Gallium Arsenide substrates give a generational advance in the control of the carrier density of states. This material advance has led to significant device technology advances in the critical wavelength range of 1.1 to 1.3 microns. This wavelength range is crucial both for low-cost wired passive optical networks and advanced multiple antenna systems. The research performing partners are leaders in the study and development of quantum dot devices and systems. Through the QUATERNIAN proposal these research performing institutions will assist these high-growth SMEs in the adoption and further development of quantum dot technology. The QUATERNIAN project strengthens the competitiveness of the European economy, the sustainability of the European research area and maintains European technology leadership.

The PHASORS project targets the development and applications of fibre based Phase Sensitive Amplifier (PSA) technology in 40Gbit/s broadband core networks, and seeks to provide Europe with a lead in this important yet relatively unexplored area. PSAs have the potential to be a disruptive technology within future optical communications, enabling ultra-low noise amplifiers and a host of important ultrafast optical processing functions for networks employing high spectral efficiency phase encoded signals.\n \nSpecifically PHASORS will:\n\n(1) Develop a reliable technology base for the realisation of practical, cost effective, PSAs and will advance the state-of-the-art in phase-locked pump systems, narrow linewidth lasers, high power amplifiers and lasers, and high performance nonlinear fibres.\n\n(2) Investigate both interferometric and non-interferometric fibre based approaches to PSA. \n\n(3) Demonstrate a PSA with a record noise figure of less than 1dB.\n\n(4) Demonstrate the benefits of the low noise properties of PSA for transmission applications.\n\n(5)Demonstrate the use of PSAs within two different application spaces:\n\tPhase sensitive optical sampling at data rates of > 40 Gb/s; \n\tOptical regeneration of phase modulated data signals at data rates >40 Gb/s.\n\nPHASORS is therefore fully aligned with the objectives of ICT-2007.3.5: Photonic components and subsystems and directly addresses several of its target outcomes by developing high performance lasers and using them together with optical fibres for high performance within specific applications in phase-sensitive parametric amplification. If successful, the PHASORS technology will have a significant impact in enabling scalable, future-proof and cost effective broadband core networks at 40Gb/s or beyond per channel. The high performance components developed will also have applications in a range of other non telecom applications including sensing, aerospace, metrology and medicine amonst others.

The Mode-Gap project targets the 100 fold enhancement of the overall capacity of broadband core networks, and seeks to provide Europe with a lead in the development of the next generation internet infrastructure that will soon be desperately needed if we are to keep pace with societies ever increasing data-transmission requirements. It is now recognized that research results are within a factor of 2 of fundamental capacity limits, bounded by fibre nonlinearity and the Shannon Limit and radical approaches now need to be investigated if we are to avert grid-lock on the internet. Mode-Gap will develop multi-mode photonic band gap long haul transmission fibres, and associated enabling technologies. These fibres offer the potential of order of magnitude capacity increases through the use of multiple-input-multiple-output operation of the multi-mode fibre capacity and further order of magnitude capacity increases through the ultra low loss and ultra-low nonlinearity offered by multi-mode photonic bandgap fibre.Specifically MODE-GAP will:\tDevelop ultra-low loss (0.1 dB/km) multi-mode (>10 modes) photonic band gap transmission fibre (MM-PBGF).\tDevelop novel rare earth doped optical amplifiers for the new transmission windows necessary for the achievement of ultra-long links.\tDevelop sources and detector arrays operating within the 1.8 to 2.1 um region\tDevelop MIMO arrangements for coupling source arrays to multi-mode fibre and multi-mode fibre to detector arrays\tDevelop MIMO and dispersion compensation signal processing algorithms applicable to both conventional solid core (glass and POF) fibres and MM-PBGF.MODE-GAP is therefore fully aligned with the objectives of ICT-2009.3.7 and directly addresses several of its target outcomes by developing photonics technologies, components and (sub) systems driven by key applications/social needs and using them to fulfil the EU vision of future-proof networks and systems enabling unlimited bandwidth enablingmore optical processing and very high spectral-density transmission and the reductionof power consumption at the system and component level with the ultimate goal ofenabling increasing information throughput. If successful, the MODE-GAP technologywill have a significant impact in enabling future proof networks and systems ofincreasing information throughput. Without such a breakthrough the internet of thefuture will be severely compromised. The fundamental research needed to avoid this needs tobe undertaken now.

The exponentially increasing capacity demand in information systems will be met by carefully exploiting the complementary strengths of electronics and optics1,2. Optical signal processing provides simple but powerful pipeline functions that offer high speed, low power, low latency and a route to densely parallel execution3. A number of functions such as modulation and sampling4-7, complex filtering8 and Fourier transformation have already been demonstrated. However, the key functionality of all-optical quantization has still not been addressed effectively. Here, we report an all-optical signal processing architecture that enables, for the first time, multilevel all-optical quantization of phase-encoded optical signals. A four-wave-mixing process is used to generate a comb of phase harmonics of the input signal, and a two-pump parametric process to coherently combine a selected harmonic with the input signal, realizing phase quantization. We experimentally demonstrate operation up to six levels. © 2011 Macmillan Publishers Limited. All rights reserved.

An efficient phase preserving amplitude noise limiter suitable for constant envelope phase-modulated signals is experimentally demonstrated for 10-Gb/s differential phase-shift-keying (DPSK) signals exploiting injection locking in Fabry-Pérot lasers. The limiter operates successfully over a 16.4-nm tuning range leading to 12 dB of power penalty reduction for $10 - 3 of bit-error-rate (BER) performance. © 2006 IEEE.

In this study, a phase-preserving limiter based on injection locking a semiconductor laser is fully investigated as an amplitude limiter for 10 Gb/s constant envelope phase encoded signals. A theoretical analysis on the modulation bandwidth and the modulation transfer function of the injection locked laser is carried out targeting to identify the operational characteristics and the regeneration properties of the proposed amplitude limiter. The theoretical analysis demonstrates the potential of the specific limiter to amplify 25 Gbaud phase modulated signals with simultaneous regeneration of its amplitude properties. Subsequently an experimental investigation demonstrates the performance of the proposed regenerator and addresses its potential exploitation in future optical networks. The specific limiter exhibits significant amplitude noise squeezing capability and extreme implementation simplicity. © 2011 IEEE.

A wavelength tunable optical comb is generated based on the gain-switching of an externally seeded Fabry-Pérot laser diode. The comb consists of about eight clearly resolved 10GHz coherent sidebands within 3dB spectral envelope peak and is tunable over the entire C-band (1530 to 1570nm). The optical linewidth of the individual comb tones is measured to be lower than 100kHz, and the RIN of the individually filtered comb tones (←120dB/Hz) is shown to be comparable to the entire unfiltered comb (← 135dB/Hz). Besides, expansion of the tunable gain switched comb is achieved with the aid of an optical phase modulator, resulting in near doubling of the number of comb tones. © 2011 Optical Society of America.

Video, mobile and cloud have driven network bandwidth to grow at astonishing rates, estimated at about 40% growth year over year. Between 2000 and 2009 channel data rates in commercial optical fibre networks were peaking at 10Gb/s. Introduction of coherent technology caused a step change and around 2011 rates jumped to 100Gb/s for long haul transmission. It was enabled by advances in digital signal processing, narrow linewidth lasers, coherent receivers and optical modulators. Such modulators are used to control both the level and phase of the optical signal to send data and are the main topic of this proposal. State of the art modulators are based on a common optical transmitter circuit (a Mach-Zehnder Modulator) to encode the data. In 2012 researchers at the Univ. Southampton invented a new device and applied for a patent on the concept. It is based on optical injection locking (OIL) and allows directly modulated lasers to be used to encode the data. Demonstration systems were developed in partnership with Eblana Photonics who provided the OIL laser devices and is the exclusive licensee to the patent IP. Eblana, established in Dublin in 2001, provides laser sources for sensing and high volume comms applications. The technique has received strong interest from the scientific community and, significantly, network system manufacturers who have stated eagerness to trial prototypes. Differentiators are that the output is linear, drive electronics are fundamentally simpler and uses half the number of high speed connections compared to the competition. Key advantages include low cost, low power consumption and amenable to miniaturisation to very small sizes. Coherent 100G transmission will migrate to shorter reach and wider usage in metropolitan networks (60-800km range) and in enterprise and access at shorter distances and these are the market focus. Eblana Photonics will exploit this technology to become the highest volume supplier of such modulators in the world.
