EDGE-EMITTING LIGHT-EMITTING DEVICE HAVING IMPROVED EXTERNAL LUMINOUS EFFICIENCY AND SELF-SCANNING LIGHT-EMITTING DEVICE ARRAY COMPRISING THE SAME

摘要

A self-scanning light-emitting element array using an end face light-emitting thyristor having improved external emission efficiency is provided. To improve the external emission efficiency of the end face light-emitting thyristor, the present invention adopts such structure that the current injected from an anode is concentrated to near the end face of the light-emitting thyristor. A self-scanning light-emitting element array is implemented by using such end face light-emitting thyristor. IMAGE
