ABSTRACT:
An optical semiconductor device having an active region defined between a pair of semiconductor regions, the active region having an incident end face through which light is introduced and an emission end face through which light is emitted. This device is designed to continuously change the distribution of the density of carriers injected in the active region over the area between the light incident side and the light emission side, thereby changing the density of carriers in the active region from the incident end face to the emission end face.
