Pulsed laser deposition of Ga‐La‐S chalcogenide glass thin film optical waveguides
KE Youden, T Grevatt, RW Eason, HN Rutt… - Applied Physics …, 1993 - pubs.aip.org
Thin film optical waveguides of the chalcogenide glass Ga-La-S have been deposited on
substrates of CaF2 and microscope glass by the technique of pulsed laser deposition. The
chalcogenide properties of photobleaching, photodoping, and photoinduced refractive index
changes have been observed and preliminary experiments carried out. The refractive index
and thickness of the layer were verified using a waveguide “dark mode” analysis technique.
Non-oxide, chalcogenide glasses are of interest for applications in infrared technology …
