Silicon Photonics for High-Bandwidth Wireless Links and Remote Sensing

Project description:
The exponential growth of the use of mobile devices, the interconnected environment and ‘smart’ cities require a dramatic increase in network capacity over the next decade. By 2020, it is expected that 50 billion devices are connected to the internet, a large part of these wirelessly. The required wireless bandwidth is, however, far beyond what technologies like WiFi can deliver.

Governments all over the world have opened up new frequency bands for such wireless communications. The current level of technology is not able yet, though, to provide low cost and compact transceivers for these frequency bands, which is a crucial requirement for ubiquitous and mobile interconnected devices. Moreover, no feasible technology exists for the next generation higher frequency bands.

Optical chips are far more suitable than electronics to generate high-bandwidth signals at these frequencies, but until recently this technology was too experimental and not robust. Over the last few years, however, foundries with mature fabrication processes have been set up to fabricate silicon based optical chips. For the first time, we can now use this optical chip technology to realise low cost, compact and high-bandwidth transceivers that enable the next generations of wireless internet. This project aims to achieve scientific and technical breakthroughs required to leverage on silicon photonics co-design of transceivers for high speed wireless communications.
