Paper Abstract

A new monolithic dual-mode laser/detector diode which functions both as a laser and a photodetector is described. A laser threshold current of 0.52A was obtained under pulsed operation in broad-area laser/detector diodes (120μm x 350μm) with differential quantum efficiencies of about 30.9%. In the detector mode at the operating wavelength of 905nm, responsivity as high as 0.43A/W was obtained with a reverse bias of 8.0V. Using dual-mode diodes instead of separate lasers and detectors would simplify monolithic integration of optoelectronic circuits.
