Abstract
We report the integration of a hybrid silicon evanescent waveguide photodetector with a hybrid silicon evanescent optical amplifier. The device operates at 1550 nm with a responsivity of 5.7 A/W and a receiver sensitivity of -17.5 dBm at 2.5 Gb/s. The transition between the passive silicon waveguide and the hybrid waveguide of the amplifier is tapered to increase coupling efficiency and to minimize reflections.

Electric field screening by photogenerated holes in multiple quantum wells: A new mechanism for absorption saturation

TL;DR: In this paper, the authors observed saturation in the electroabsorption of InGaAs/InP multiple quantum wells (MQWs) at high optical intensity, and they found that saturation occurs due to the presence of trapped photogenerated holes that screen the MQWs from the applied electric field.
