Method of manufacturing masked semiconductor laser

摘要

A masking layer is formed on the light-emitting mirror surface of a semiconductor laser body. The masking layer is capable of blocking light emitted from the semiconductor laser body and of being thermally melted and evaporated by exposure to the emitted light. When the masking layer is formed on the light-emitting mirror surface of the semiconductor laser body, a small light-emitting hole is defined in the masking layer by the heat of the emitted light which is effective to prevent the material of the masking layer from being evaporated on a portion of the light-emitting surface.
