Abstract
An edge-emitting thyristor having an improved external luminous efficiency and a self-scanning light-emitting device array comprising the edge-emitting thyristor are disclosed. To improve the external luminous efficiency of an edge-emitting light-emitting thyristor, a structure where the current injected from an electrode concentrates on and near the edge of the light-emitting thyristor is adopted.
