Transverse modal behavior of transverse junction stripe laser excited by short electrical pulse

Abstract

The transverse modal behavior of the transverse junction stripe (TJS) laser excited by short (70 ps) electrical pulse is investigated experimentally and theoretically, It is predicted theoretically and observed experimentally that the transverse mode strongly depends on the excitation pulse amplitude and the dc bias current (which is set below threshold), This dependence is found to be due to transient lateral carrier diffusion at the lasing junction.
