Abstract

PURPOSE:To irradiate and stop the light having any wavelength preset in response to the irradiation and stop of an external light in a light controlled semiconductor light emitting element by forming a light absorbing region for optically shielding both a light switching region and a light emitting region therebetween. CONSTITUTION:A light emitting element consists of a light switching region formed on GaAlAs layers 1, 2, 3, a light absorbing region made of GaAs layer 4, and a light emitting region made of GaAlAs layers 5, 6, 7. When input light (a) is irradiated thereto, the light switching region becomes conductive to supply a current from the bias voltage supply source 14 to the light emitting region to flow a forward current to a PN junction included therein to generate an output light (b) therefrom.
