Abstract

PURPOSE: To obtain a semiconductor light coupling device which does not require matching of optical axes, and has high light transmission efficiency and response speed. by composing an electrically insualted light emitting part an dlight receiving part by dividing a semiconductor formed on one side of an insulating or semi-insulating solid substrate, and using the insualted portion as a light medium.
