Dependence of T0 on P-Cladding Layer Doping Level in InGaAsP Lasers

Abstract
The effects of the doping level in the P-cladding layer on the T 0 of InGaAsP lasers have been investigated. A threshold temperature parameter T 0 as high as 90 K has been observed. A new laser structure which involves a simple modification scheme applicable to most laser structures with improved temperature sensitivity has been demonstrated.
