Chip-scale si-photonics optical transceiverfor a photonics-electronics convergence system (invited paper)

Here, we introduce the roadmap of the PETRA project. The first approach is a chip-scale silicon photonics transceiver using multimode optical wiring to realize low-cost and high-productivity optical interconnection for several shortreach applications. Hybrid-integrated low-power-consumption chip-scale optical transmitters/receivers called "optical I/O cores" are presented. Their performance can cover most reach demands for high-performance computers and data centers. The scope for advances in technology based on optical I/O cores is discussed for application of this concept to future photonics-electronics convergence at the chip level.
