NAME

Semiconductor lasers

DESCRIPTION

Semiconductor lasers use the optical properties of semiconducting materials to produce coherent light. Electrons and their positive-charge counterpart called holes are injected into an optically active region where they combine together and generate photons. Reflection of light from semiconductor–air or semiconductor–semiconductor interfaces proved the necessary optical feedback.
