Advanced photonic integrated circuit building blocks for reconfigurability in hyperscale data centres

1Resolute Photonics, Ireland; 2University of St Andrews; 3Senko Advance Components
In this talk we introduce two new European projects DYNAMOS and ADOPTION, which will develop advanced integrated photonic technologies for WDM hyperscale data centre architectures including a novel stamped metallic micro-mirror array for advanced PIC-to-fibre coupling with the potential to dramatically reduce PIC design and assembly costs. We also discuss international standardization efforts for these corresponding optical interconnect technologies for future hyperscale data centre, HPC and 6G and Quantum environments.

We review our recent progress on advanced silicon photonic devices and photonic circuits, including advanced grating couplers, modulators, mode and polarization division multiplexing and integrated optical signal processors for use in high capacity data center interconnects. The use of shifted polysilicon overlay gratings on waveguide grating couplers to improve coupling efficiency and polarization independence will be described. We also present our recent results on silicon microring and silicon-germanium electroabsorption modulators for 100Gbaud data transmission and their use polarization and mode division multiplexed optical fiber interconnects. We present novel integrated optical signal processors which can unscramble the mixing of polarization and mode data lanes that will occur after fiber transmission and demonstrate 400Gb/s per wavelength intensity modulation direct-detection silicon photonic transceivers.

We discuss recent results related to the realization of integrated waveguide and fibre-based phase filtering devices for high-speed linear passive logic applications. A record frequency resolution of 1 GHz (a 10-fold improvement over standard optical waveshaper technology) is achieved using fibre Bragg grating-based phase filters. We have also succeeded in realizing Bragg grating devices with sub-mm2 device footprint based on spiral waveguides, paving the way for on-chip implementation. Using (all-pass) phase-only filtering devices, NOT and XNOR logic operations are demonstrated at ultrafast operation speeds with a few-fJ/bit energy consumption.
