Abstract :
An intracavity monitor diode with QW-absorber is integrated within the bottom Bragg reflector of an 850 nm VCSEL. Temperature-insensitive responsivities are obtained by adopting a suitable QW design for the absorber. The thermal dependence of the remaining photocurrent offset due to spontaneous emission can be minimised by a proper choice of laser detuning and position of the absorber QW inside the Bragg reflector
