    摘要： An optical amplifier includes a plurality of photon amplifying regions. Each photon amplifying region includes a bottom electrode, an insulating layer formed over the bottom electrode, and having a through hole to the bottom electrode, a semiconductor layer and a top electrode formed over the semiconductor layer, wherein the top and bottom electrodes electrically contact the semiconductor layer. The semiconductor layer is formed over the insulating layer and in the through hole, and has a semiconductor active region in the through hole. The semiconductor active region has a direct electronic band gap with a conduction band edge, and is embedded within a photonic crystal having an electromagnetic band gap having photon energies overlapping the energy of the conduction band edge of the electronic band gap such that spontaneous emission of photons in the semiconductor active region is suppressed.

    摘要： An optical system for detection of atmospheric ice particles is described. The optical system includes a laser light source configured to emit laser light, a photodetector, a first lens element and detection electronics. The first lens element is arranged to image light from the laser light source onto a measurement volume, and to direct scattered light received from the measurement volume to the photodetector. The detection electronics is connected to the photodetector, and is configured to receive a light detection signal from the photodetector and to indicate whether or not the atmospheric ice particles exist in the measurement volume based on the light detection signal.
