System embedded photonic interconnect has been a strong area of focus in the European funding programmes for collaborative research and technological development over the past 15 years. This is particularly evident in projects from the Sixth Framework Programme (FP6), which ran from 2002 – 2006, the Seventh Framework Programme (FP7), which ran from 2007 – 2013 and the current Horizon2020 programme, which started in 2014 and is due to end in 2020.

The implementation of compact, dense WDM transceivers in Silicon Photonics (SiP), that are sufficiently cost and power efficient for Data Centre applications, is a notably challenging endeavour. Semiconductor Mode Locked Lasers (MLL) and Resonant Ring Modulators (RRM) have been proposed as key devices for an elegant and efficient transceiver architecture. In recent works, we have shown that single section passively modeMlocked MLLs can generate adequate optical carriers for 14 Gbps and 25 Gbps serial communications with onMoff keying modulation. A systematic analysis of the optical power budget of a solution comprising a MLL, an array of RRMs driven by hybridly integrated chipMscale electronics, and a Semiconductor Optical Amplifier (SOA) has also been reported . At the 2017 European Conf. on Integrated Optics we will be reporting on recent progress towards integration of this transceiver architecture.

Increasingly complex and high capacity optical switch fabrics are being proposed and demonstrated for high-bandwidth data streams in datacentres. Mach-Zehnder interferometer (MZI) and semiconductor optical amplifier (SOA) based switches have received much attention owing to their nanosecond response time which is essential for packet switching. However, the scalability of MZI switches is inherently limited by insertion loss and accumulated crosstalk, whilst the scalability of SOA switches is restricted by accumulated noise and distortion.

Abstract: Flexible multimode polymer waveguides are shown to maintain bandwidth length products > 300 GHz×m for bend radii as low as 3 mm under restricted launch, with < 0.7 dB excess bend loss.
