Modulated photonic-crystal surface-emitting laser with elliptical lattice points for two-dimensional coupling enhancement

open access: yesAIP Advances, 2019
Modulated photonic-crystal surface-emitting lasers (M-PCSELs) are new semiconductor lasers that can emit a laser beam in arbitrary directions. Therefore, they can be regarded as a next-generation light source for light detection and ranging.

Optical Dispersion In Annealed Thin Films of S-doped a-Si:H Alloys [PDF]

open access: yesЖурнал нано- та електронної фізики, 2013
S-doped amorphous hydrogenated silicon (a-Si,S:H) thin films were prepared by conventional PECVD method on corning glass substrates. The prepared thin films were subsequently annealed in vacuum (~ 2 × 10 – 6 Torr) in the temperature range from 100 °C to ...
