Hybrid integration of a 4 -- channel semiconductor optical amplifier array onto a silicon photonic carrier with integrated SiN waveguides has been demonstrated. Custom packaging features are designed into the silicon photonic carrier, including efficient waveguide optical coupling structures, an etched trench with metal lines and AuSn solder pads for SOA integration, and vertical reference stops for...
We discuss silicon photonic switch fabric designs that target data-intensive computing networks, reviewing recent results, and projecting future performance goals. We analyze the achievements of demonstrated hardware in terms of switching time, footprint, crosstalk, and power consumption, concluding that the most crucial metric to improve upon is net loss. We propose integrating semiconductor optical...
Data-intensive computing increasingly involves operations at the scale of an entire computing system, requiring quick and efficient processing of massive datasets. In this article, the authors present a circuit-switched network architecture, together with requisite optical-switch and burst-mode transceiver technology, designed to support demanding graph algorithms in a distributed-memory system. The...
This paper reports on the evaluation of high-speed signaling performance of multilevel metallic interconnects on glass substrates. The wafer fabrication, transfer process, and passive electrical characterization of interconnects are addressed. Measurement results demonstrate less than 5 dB/cm insertion loss below 20 GHz. Moreover, 2-level wiring on glass with inter-level vias is utilized to implement...
We report here on the design, fabrication and characterization of an integrated optical data bus designed for terabit/sec-class module-to-module on-board data transfer using integrated optical transceivers. The parallel optical transceiver is based on a through-silicon-via (TSV) silicon carrier as the platform for integration of 24-channel VCSEL and photodiode arrays with CMOS ICs. The Si carrier...
