Abstract

PURPOSE: To obtain a light emitting element suitable for combination with an optical fiber by restricting the light emitting region of a PN junction part to an extremely small portion to cause light emission of high brightness and high efficiency, providing a diffused layer of a high carrier concentration at the contact portion with an electrode layer to reduce contact fdifusion an furtherd maintina the lower reduce contact diffusion and further maintain the low carrier concentration for optical path to reduce light absorption.
