Abstract
We have studied the effect of laser cavity parameters on the light – current characteristics of lasers based on the AlGaInAs/GaInAsP/InP solid solution system that emit in the spectral range . It has been shown that optimisation of cavity parameters (chip length and front facet reflectivity) allows one to improve heat removal from the laser, without changing other laser characteristics. An increase in the maximum output optical power of the laser by has been demonstrated due to cavity design optimisation.
