Photonic-well microcavity light emitting devices |
摘要 |
A photonic light emitting device comprising a relatively high refractive index photonic-well semiconductor waveguide core in the form of an arcuate shape, linear shape and combinations thereof. The waveguide core is formed into a closed loop cavity for a light-emitting device or laser. The waveguide core is surrounded by relatively low refractive index medium and comprises an active medium having major and minor sides and semiconductor guiding layers proximate the major sides. The active medium and the guiding layers are so dimensioned in a transverse direction relative to the path of light propagation through the core to provide significantly increased spontaneous-emission coupling efficiency, leaading to low lasing threshold and high intrinsic modulation rates. |
