Abstract :
A waveguide-integrated black phosphorus photodetector with high responsivity and low dark current is demonstrated for telecom wavelengths with an RC-limited bandwidth of 3 GHz. Electrostatic doping and frequency dependent photoresponse are used to identify photocurrent generation mechanisms.
