Abstract
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.
