Over 100 Gb/s Four-level Pulse-Amplitude Modulation (PAM4) Vertical-Cavity Surface-Emitting Laser (VCSEL) based optical interconnects require high speed, damped, and low relative intensity noise (R…
A Si-Ge waveguide avalanche photodiode with extremely high temperature stability is demonstrated. The breakdown voltage increases ~4.2 mV/°C, bandwidth reduces ~0.09%/°C, and gain-bandwidth produ…
