The demand for broadband content and services has been growing at tremendous rates, and predictions indicate that wireless data-rates of multiple tens of Gbps will be required by the year 2020, essentially for short-range connectivity. Currently available wireless technology cannot support these future demands, and so there is an urgent need to develop new technology platforms that are cost and energy efficient to enable ubiquitous ultra-broadband wireless communications seamlessly integrated with high-speed fibre-optic networks, paving the way for 100 Gbps datarates in the long term. The frequency spectrum currently in use is not expected to be suitable to accommodate the predicted future data-rate requirements, and therefore there is a need to embrace higher frequency bands, above 60 GHz and up to 1 THz. iBROW aims at developing a novel, low cost, energy-efficient and compact ultra-broadband short-range wireless communication transceiver technology, capable of addressing predicted future network usage requirements. This will be pursued through the exploitation of Resonant Tunnelling Diode (RTD) devices which represent the fastest pure solid-state electronic devices operating at room temperature with reported working frequencies exceeding 1 THz. Through the development of a unified technology that can be integrated into both ends of the wireless link, namely consumer portable devices and fibre-optic supported base-stations, the project aims at increasing the RTD output power, optical detection efficiency and energy efficiency at target frequencies, developing a methodology for low cost RTD manufacturing on a silicon platform, photonic integration and packaging, as well as identifying appropriate communication methods and architectures to enable its deployment in 10 Gbps short-range wireless communication devices in short term and paving the way for 100 Gbps in long term for both the mm-wave and THz frequency bands, seamlessly integrated with optical fibre networks

This project targets the development of compact and low power transceivers that enable wireless data transfer at sub-terahertz carrier frequencies and their application to future high data-rate short-distance communication links. The interest of the topic relies in the fact that advances in semiconductor technology, favourable spectrum policy and demand for gigabit throughput capabilities have created an opportunity for millimetre wave radio technology above 100GHz. The iPHOS research plan aims to address what has been identified as the Achilles heel of systems operating in this frequency range: the lack of reliable, compact low cost sources which can give rise to commercially successful products.\nWe propose optical techniques to generate the carrier wave, enabling us to integrate a high level of functionality such as tunability of the carrier wave and modulation to superimpose data. The carrier frequency will result from beating two optical modes from dual mode laser on a high speed photodiode with an integrated antenna. The technical challenge that iPHOS is going to address is the integration of all of these elements on a single chip, including dual-wavelength sources, passive waveguide for optical couplers and connecting waveguides, electro-optical modulators for data encoding and high speed photodiode for electro-optical conversion. This challenge will require a strong effort on chip integration. In addition, advanced packaging technology will contribute to the goal of providing a compact and rugged system.\nThe first application field targeted by iPHOS are future on-board flight entertainment systems, effort led by partner THALES. Nevertheless iPHOS impact strategy includes channeling the designs and devices obtained through licensing design libraries within the European manufacturing platforms of JePPIX and ePIXpack, opening up the possibility for other companies and consortiums to incorporate the mm-wave sources in other fields of applications.

CSTG Proposes to develop a high power red laser diode for digital cinema projector, Laser TV and conference room projector manufacturers, as part of the projector’s RGB light source. This Proof of Concept project will be carried out as a follow on from a Proof of Market project which assessed the commercial viability for CSTG to develop such laser diodes. Laser based cinema projectors offer significant advantages over current largely Xenon bulb based equipment. Xenon bulbs are power inefficient and have short bulb lifetime. Laser based cinema projectors offer high efficiency, long lifetime and a much wider colour space, which delivers significantly deeper colours and higher brightness. A laser based cinema projector requires red, green and blue lasers, each producing from 50 to 200 Watts. For the red laser this could be satisfied by combining the output of a number of red laser diode bars. The red laser in such a projector system (which is the subject of this project) ideally emits light at a wavelength between 630 nm and 640 nm. This is where the responsivity of the human eye to red light is maximised. This particular wavelength requirement leads to additional challenges for diode laser technology in the areas of: thermal performance, facet coating and passivation, process yield, submount configuration and speckle reduction, all of which present significant challenges. The total worldwide market for red laser diodes in entertainment display was $32M in 2010, is forecasted to grow at 20% per year and reach $50M to $100M in the next 5 to 7 years. Thus there is a significant commercial opportunity if the required laser diode can be developed. As prices reduce, lower cost and higher volume projectors will start to use laser diodes for their light sources and it is anticipated that other applications for high power red laser diodes will also emerge.

Existing optical networks are driven by dynamic user demands but operate statically at their maximum performance and do not offer much adaptability. Thus the links are not energy-efficient. ADDAPT aims at the development and technology take-up of dynamic transceiver subsystems. By implementing performance and power adaptivity from system down to optical device, electrical circuit and transistor level, flexible energy-efficient optical transmission links are enabled which pave the way for massive reductions of CO2 emission and costs.Depending on the actual data load, the number of activated link paths and individual device parameters like bandwidth, clock rate, modulation format and gain are adapted to enable lowering the supply power. Several control types are investigated: cognitive adaption based on predetermined or time averaged loads and real-time adaption. Driven by control units including smart algorithms, the devices can be tuned from 8 to 56 Gb/s. Novel adaptive directly modulated lasers and photodetectors designed for near-field light coupling are developed to allow self-aligned low-cost waveguide assemblies with minimum optical power losses. Laser bandwidths beyond 30 GHz and power consumption can be traded off and controlled by driver circuits. Circuits such as amplifiers, drivers and clock data recoveries are designed in energy-efficient 32 nm CMOS and can be adjusted via current sources, dc/dc converters and switches. High-speed, low-loss packaging solutions using glass or ceramics are developed. An optical communication platform tailored for data centers is designed with 12 link paths and 10 m link distance for verification of speed adaption from 0.672 Tb/s to 8 Gb/s with power saving factors of up to 20.ADDAPT is market and standard driven and combines the complementary competences of 3 large companies, 3 SMEs and 2 universities including device manufacturers, suppliers of communication equipment and network operators from 7 EU/associated countries.
