Chip-scale Si-photonics optical transceiver for a photonics-electronics convergence system

We propose a chip-scale silicon photonics transceiver using multimode optical wiring to realize low-cost and high-productivity optical interconnection usable for several short-reach applications. We also present hybrid-integrated low-power- consumption chip-scale optical transmitters/receivers called “optical I/O cores.” The optical I/O cores provide clear eye opening in a wide range of temperature operation without clock data recovery. We show the design of one such optical I/O core and evaluate its performance for a wide range of temperatures. Finally, we introduce an example of LSI system based on the optical I/O approach.
