High-Performance 850 nm VCSEL and Photodetector Arrays for 25 Gb/s Parallel Optical Interconnects

Abstract

We design, fabricate and demonstrate 850 nm VCSEL and PD arrays which operate at 25 Gb/s per channel, up to 600 Gb/s with 24 channels, for low-power parallel optical module applications. We also report a complete 25 Gb/s VCSEL to PD back-to-back link.
