QUANTUM DOT SLAB-COUPLED OPTICAL WAVEGUIDE EMITTERS

摘要

An optical apparatus comprises a semiconductor substrate and a slab- coupled optical waveguide (SCOW) emitter disposed on the semiconductor substrate. The SCOW emitter comprises an optical waveguide comprising: a first region doped with a first conductivity type; a second region doped with a different, second conductivity type; and an optically active region disposed between the first region and the second region. The optically active region comprises a plurality of quantum dots.
