Abstract

PURPOSE: To minimize the threshold current and the range of temperature change of threshold current, by reducing the width of forbidden band of the second semi-conductor layer or injection type laser composed of four layers formed on the substrate, in comparison with the width of forbidden bands of the first, third and fourth semiconductor layers.
