Abstract

In this paper we report the effects of relatively weak magnetic fields (up to 2T) on the threshold current, temperature characteristics and output power of AlGaInP MQW laser. The threshold current and temperature characteristics increased while the output power decreased by applying the magnetic field at different directions with respect to the quantum well plane. This paper presents a new insight into the mechanism that influence changes in the properties of MQW laser on application of magnetic fields based on the dynamics of electron-hole recombination.
