Waveguide-Integrated Ge/Si Avalanche Photodetector with 105GHz Gain-Bandwidth Product
Avalanche photodiodes
2015/6/4
We report the first demonstration of a waveguide-integrated avalanche photodetector using Group-IV heterostructure materials. Such device achieved a responsivity of ~0.8A/W at unity gain and an impres...
Method for Measuring Conversion Gain Response and O/E Bandwidth of Integrated D(Q)PSK Receivers
photodetectors integrated optoelectronic circuits
2015/6/4
A method for recovering the O/E frequency response of D(Q)PSK receivers with integrated delay-line interferometers (DLIs) is presented. Modulator chirp is canceled by measuring at specific DLI phases,...
