Abstract
A semiconductor light emitting device has a semiconductor light emitting element section and an n-type semiconductor substrate with a through hole which serves as a window through which light generated by the semiconductor light emitting element section is emitted. The device further includes a p-type region formed in the semiconductor substrate and facing the through hole. The p-type region and the semiconductor substrate constitute a photodiode.
