waveguide, Rings, Multiplexing and De Multiplexing functions, like MMI and MZI, plus high-speed, active devices such as silicon electro-optic modulators (MZM, RRM) and germanium photodetectors, while maintaining thermal tuning capabilities using metal heaters. Typical measured insertion loss for O-band (1260- 1360nm) devices is -2.0dB with a -1dB bandwidth of 26nm and a back reflection in the -20 to -25 dB range. Waveguide insertion losses are below 2dB/cm and 0.2dB/cm for monomode and multimode waveguides, respectively. Germanium photodiode responsivity is up to 0.75A/W with a bandwidth >30GHz. design kit (PDK), which will be available using a variety of EDA tools, and includes layout, verification and simulation capabilities. The technology is fully supported by a process technology. Applications such as high capacity links for disaster recovery situations have also been discussed. Consumers can look forward to faster, clearer services, greatly reduced download times, better connectivity and seamless access to services, entertainment and media. These radios operate in the 71-76 and 81-86 GHz frequency bands, this offers a real advantage in that these bands only require a light licence, this provides further savings in terms of time and cost. RF Com’s Managing Director, Ian Cains says, ‘this is a landmark day for us as a business, but also for the UK market. It will now be possible to offer a solution that is ready now to provide the fastest, most accessible network anywhere globally. We are incredibly excited about working with ELVA-1 on embedding this technology into the UK market – we’ve already had a huge amount of interest from mobile operators, wireless internet providers and fibre optic providers’.

Adtran to develop tunable optics for NG-PON 2 Adtran has announced development of its first Subscriber Edge Tunable (SET) optical transceivers, to address several key technology and innovation gaps that have hindered market development for multi-wavelength access networks. According to Adtran, the new tunable 10G optics could save network providers up to 80 per cent in capital and operational costs as they look to upgrade their access infrastructure: “With our new SET optical transceivers, Adtran Labs is VTT and PhoeniX Software develop Si photonics kit addressing the most significant challenge for the economics of NG-PON2.” Supported by the EU-funded ACTPHAST project, VTT Technical Research Centre of Finland and PhoeniX Software have developed a process design kit to support the development of silicon photonics. The kit includes design rules, component examples and simulation models as documents and as a software library for PhoeniX Software solutions. Silicon photonics is under intensive development worldwide in a bid to enable fast optical communication in data centres and other key infrastructures of our digital society. Another goal is the production of affordable and precise sensors for diverse applications.
Within the framework of the Nanoelec Research Technological Institute (IRT) and thanks to developments realised within the European FP7 PLAT4M project, CEA-Leti have been able to provide a very low-cost way to address the challenges of achieving miniaturisation and high- density components. The company’s new MPW, on a 310nm SOI platform, has opened the door for users to create products for long-haul telecom, short- reach Datacom and optical switching in datacentres. The CEA-Leti CMOS 200mm clean room facilities provide an affordable access for prototypes and low volume production of Photonic ICs through two MPW Europeans brokers, Europractice and CMP. The new technology offers high performance grating couplers and options for silicon patterning that allow the design of various passive, also benefit, their customers enjoying enhanced download speeds. The deployment of wireless systems being both fast and relatively low cost, these full duplex, zero footprint systems will provide fast efficient roll out. The technology also lends opportunity to provide “Last Mile” solutions with improved performance and lower costs. Full 10 Gigabit performance gives comparable speeds to the best existing optical networks. One consequence of this will be no more road and pavement digging all the way to the consumer, says RF Com. Internet Protocol TV and Corporate Campus Networks are also applications where great benefit will be derived from the PPC-10G itself to complimenting new and existing fibre optic networks, with the
can be used to track the position of the detector and point it to the laser, but these approaches add quite a bit of complexity. The new light collector uses plastic optical fibers containing organic dye molecules that absorb blue light and emit green light. This setup replaces the classical optics and motion platform typically required to point the light to the collection area. “The fact that these fluorescent optical fibers emit a different colour than they absorb makes it possible to increase the brightness of the light entering the system,” said Tiecke. “This approach has been used in luminescent concentrators for solar light harvesting, where the speed of the color conversion doesn’t matter. We showed that the same concept can be used for communication to circumvent pointing and tracking problems while accomplishing very high speeds.” Gigabit system, they see this as an opportunity to provide enhanced services, where increased speeds would allow the download of a movie to your phone or tablet within 1-2 seconds. Internet service providers will generation of radio links are up to 10 times faster than the technology in current use. When used within the backbone of mobile communication systems such as 4G / LTE and future 5G systems this technology will allow ultrafast downloads and data streaming. Several of the UK’s mobile operators have expressed great interest in the 10 UK-based RF Com in partnership with Elva-1 has announced the launch of what they are calling the world’s first 10Gbps Point to Point radio communications link.
