Abstract

Silicon photonics is envisioned as a promising solution to address the interconnect bottleneck in large-scale multi-processor computing systems, owing to advantageous attributes such as wide bandwidth, high density, and low latency. To leverage these advantages, optical proximity coupler is one of the critical enablers. Chip-to-chip, layer-to-layer optical proximity couplers with low loss, large bandwidth, small footprint and integration compatibility are highly desirable. In this paper, we demonstrate chip-to-chip optical proximity coupling using grating couplers. We report the experimental results using grating couplers fabricated in a photonically-enabled commercial 130nm SOI CMOS process.
