Abstract :
Summary form only given. Leakage current increases threshold, decreases external efficiency and reduces temperature stability of the semiconductor laser. Heterobarrier leakage in InGaAsP/InP lasers was given detailed experimental and theoretical consideration and the design approach for its reduction was developed. The details of lateral leakage are determined by the device design and several different mechanisms can contribute to the net lateral leakage current. We studied the effect of the lateral leakage current on the performance of 1.3 /spl mu/m InGaAsP multiple quantum well (MQW) capped mesa buried heterostructure lasers.
