Light source, optical pickup, and electronic apparatus

摘要

A light source of the present invention includes: a semiconductor light emitting device which has a light emitting face and emits light from part of the light emitting face; a container which has a light transmitting window for transmitting the light and accommodates the semiconductor light emitting device; and a gettering portion for performing gettering of a material containing at least one of carbon and silicon. The gettering portion is positioned, in the container, in a region other than the part of the light emitting face of the semiconductor light emitting device.
