TRANSVERSE MODE STABILISER INJECTION LASER

摘要

A transverse mode stabilized injection laser with a planar active layer is provided with a transverse waveguiding effect by the presence of a rib of intermediate refractive index material protruding through a blocking layer overlying the active layer. Optionally the blocking layer may include high refractive index material to provide additional waveguiding effect and controlled attenuation of higher order transverse modes.
