Abstract
A semiconductor light amplifier comprises a substrate, a semiconductor activation layer formed on the substrate for propagating light, and amplifying light propagated through the activation layer which has a wavelength within a predetermined range when a current is applied thereto, an electrode for applying a current to at least a portion of the activation layer, and means for imparting a loss to the light propagated through the activation layer which has a wavelength in a portion of the predetermined wavelength range.
