Abstract
An intracavity monitor diode with QW-absorber is integrated within the bott om Bragg reflector of an 850nm VCSEL, Temperature-insensitive responsivitie s are obtained by adopting a suitable QW design for the absorber. The therm al dependence of the remaining photocurrent offset due to spontaneous emiss ion can be minimised by a proper choice of laser detuning and position of t he absorber QW inside the Bragg reflector.
