Abstract
A light emitting device has an indium gallium arsenide phosphide luminescent layer between a first clad layer of n-type indium phosphide and a second clad layer of p-type indium phosphide, and a strained barrier layer of p-type indium aluminum arsenide is inserted between the luminescent layer and the second clad layer so as to increase the potential barrier therebetween, thereby improving the luminous efficiency and the saturation point of the light output.
