The need for higher speed is a never ceasing requirement for broadband access and requirement of 1 Gbps is expected around 2016. The copper lines are expected to reach their maximum capacity at about 10Mbps while the capacity required only for watching one channel of HDTV is 20Mbps. Tithe total number of homes connected to fibres will grow from about 11 million at the end of 2006 to about 86 million at the end of 2011, dominated by Asia with 59 million household connected. Our idea is to develop and implement WDM-PON as the new future proof FTTH technology to satisfy the coming BW requirements with a point to point architecture. The aim is to develop application specific optical components of a WDM-PON broadband access network targeting a system cost per subscriber below todays implementation of GPON by develop innovative new low cost components with high level of integration in addition to new manufacturing processes. Even the cheapes WDM-PON solution cost 2 -3 times as much as GPON. Up to 95% of the cost of optical components is due to packaging. The project aims to develop a system with a integration scale that is around 100 times higher than SOA that can be implemented as an upgrade of xPON systems, that are currently being installed, and will not require changes or re-routing of optical fibres. The European citizens and society will benefit from GigaWAM through: Easier access to a broad range of services; online maintaining communication links, avoiding discrimination and exclusion, benefit regarding telemedicine and eHealth, e-learning, and bridge the gap between urban and rural areas and Eastern and Western Europe. Overall, the market opportunity in year 5 post market launches is 230 Mn annually with market launch in Europe, Asia and US assuming a conservative market penetration the first years followed by a steeper growth to 5% market penetration in Europe in year 5.

PhoxTrot is a large-scale research effort focusing on high-performance, low-energy and cost and small-size optical interconnects across the different hierarchy levels in Data Center and High-Performance Computing Systems: on-board, board-to-board and rack-to-rack. PhoxTrot will tackle optical interconnects in a holistic way, synergizing the different fabrication platforms (CMOS electronics, Si-photonics, polymers, glass, III-Vs, plasmonics) in order to deploy the optimal mix&match technology and tailor this to each interconnect layer. PhoxTrot will follow a layered approach from near-term exploitable to more forward looking but of high expected gain activities. The main objectives of PhoxTrot include the deployment of:\n. generic building block technologies (transmitters, modulators, receivers, switches, optochips, multi- and single-mode optical PCBs, chip- and board-to-board connectors) that can be used for a broad range of applications, extending performance beyond Tb/s and reducing energy by more than 50%.\n. a unified integration/packaging methodology as a cost/energy-reduction factor for board-adaptable 3D SiP transceiver and router optochip fabrication.\n. the whole food-chain of low-cost and low-energy interconnect technologies concluding to 3 fully functional prototype systems: an >1Tb/s throughput optical PCB and >50% reduced energy requirements, a high-end >2Tb/s throughput optical backplane for board-to-board interconnection, and a 1.28Tb/s 16QAM Active Optical Cable that reduces power requirements by >70%.\nTo ensure high commercial impact after the end of PhoxTrot, all activities have been designed around current market roadmaps that will be updated during the course of the project and are led by industrial partners. PhoxTrot brings together the major European industrial and research players in the field. In so doing it will create a highly timely thrust and of unprecedented momentum in optical interconnects in Europe with worldwide impact.

The ACTION project builds on the recent discovery that relatively low levels of pulsed infrared laser light are capable of triggering activity in hair cells of the partially hearing (hearing impaired) cochlea and vestibule. So far the excessively large volume of optical fibre systems and external light sources used for animal studies prevented the practical use of this discovery for long term animal research devices or for human grade implants. ACTION aims to develop a self-contained, smart, highly miniaturised system to provide optoacoustic stimuli directly from the electrode array of a cochlear implant system. The resultant neural cell response will be electrically recorded and direct feedback to the light source will be provided to enable automated, objective hearing threshold assessment and optimization of sound feature coding enhancements for improved quality of the acoustic sound. The new implant is aimed to lead to more effective non-contact treatment, as a device with intra-cochlear sound sources offers many potential advantages over a traditional in the ear hearing aid/speech processor combination. This approach will at the same time avoid damage of neural tissue by high electrical current, and introduction of high-frequency artifacts to the recording signal. Biocompatible, long-term implantable materials for micropackage and integration principles for the light sources (specific pulsed vertical cavity surface emitting lasers optimized for optical neurostimulation) will be selected. The project includes neural response measurements and communication between discrete elements to achieve robust and reliable miniature standalone devices with high acceptance within the medical sector. Pre-clinical tests for optoacoustic cochlear implants will be an integral part of the project.

Wavelength-tunable lasers are key components for future reconfigurable optical networks and for cost-effective and compact telecommunication infrastructures. Moreover, a broadband and continuously tunable laser with high purity emission spectrum is a versatile tool for many sensing applications, e.g. for greenhouse gases (laser absorption spectroscopy) or deformations of buildings (fiber Bragg grating sensors).\nA novel concept for widely and continuously wavelength-tunable single-mode laser diodes in the 750-2100 nm wavelength range will be developed. The underlying VCSEL structure is completed by a micro-machined moveable Bragg-mirror with a sub-wavelength grating (SWG). The single-mode property of the VCSEL structure is thus ideally combined with the polarization stability of the SWG and the wide and continuous tunability of the electro-thermally or electro-statically actuated mirror. For the fabrication of the nano-scale SWGs an electron-beam writing process will be developed.\nThe curvature of the micro-mirror will be matched to the phase front of the fundamental mode to achieve its maximum support while suppressing undesired polarization modes by means of a SWG. This technology can select the single fundamental mode from relatively large apertures. The optical output power will be high and a very good sidemode suppression will be achieved during tuning. The project will develop both long wavelength InP-based VCSELs (1.3m to 2.1m) and short wavelength GaAs VCSELs (down to 800nm), and thus introduces widely tunable VCSELs in a broad range of the optical spectrum. Additionally, a technology for integrated tunable VCSELs with dielectric Bragg mirrors will be developed for efficient manufacturing of the laser modules.\nThe devices will be optimized in close cooperation between the university and industrial partners. Devices for gas detection, fiber Bragg grating sensing and optical communications will be investigated.

The objective of FIREFLY is the introduction of novel polymer waveguide and photonic crystal structures based on highly structured 3D nano-hybrids into industrial applications by using a new cost effective production process for larger scale manufacturing. The target applications are optical waveguides and photonic structures for the manipulation of light in, for example, optical interconnects. The optical interconnects technology will initially be applied for data communication in high performance supercomputers, and eventually these optics will also find their way into high-end server systems, mid-range servers and in consumer-like applications such as high-end multimedia devices.\nWaveguides and photonic crystals based on polymers have been proven in a laboratory environment to be interesting technologies for light management. In most cases these structures are manufactured on small scale. We propose the use of a relatively new technology to manufacture these structures on a larger scale.\nThe nano-hybrids will be manufactured using a combined approach of nano-imprint process in a polymer resins and self assembly of material in the polymer nano-structures. The nano-structures will be filled with new modified polymer compositions having a high refractive index and optical clarity at relevant wavelengths, necessary for waveguides, and with inorganic nanoparticles to prepare photonic crystals, for the manipulation of light for guiding the light in waveguides through sharp horizontal and vertical bends. Some material developments are needed: new silicone polymers that will be modified for improved optical properties such as low optical loss and tuneable refractive index, and new inorganic particles that will combine a high refractive index with a very high level of monodispersity.\nThe manufacturing process will be suitable for up-scaling to an industrial process. This new bottom-up approach will enable the development of hybrid materials with new optical properties.
