High-performance 850 nm VCSEL and photodetector arrays for 25 Gb/s parallel optical interconnects

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. © 2010 Optical Society of America.
