Light absorbing layer for II-VI semiconductor light emitting devices
摘要:
A II-VI semiconductor light emitting device includes a II-VI semiconductor light emitting region and a II-VI semiconductor waveguide layer. A light absorbing layer is provided near the II-VI semiconductor waveguide layer, outside of the active region. The light absorbing layer absorbs extraneous radiation thereby reducing dark line defects (DLDs).
