Ry. Tsai et al., AMORPHOUS-SILICON AND AMORPHOUS-SILICON NITRIDE FILMS PREPARED BY A PLASMA-ENHANCED CHEMICAL-VAPOR-DEPOSITION PROCESS AS OPTICAL COATING MATERIALS, Applied optics, 32(28), 1993, pp. 5561-5566
Durable, uniform, and reproducible amorphous silicon and amorphous sil
icon nitride thin films deposited by plasma-enhanced chemical vapor de
position that are appropriate for the design and fabrication of optica
l interference filters in the near-infrared region are found. Optical
and physicalk properties of single-layer films are discussed. The dura
bility and performance of Fabry-Perot interference filters and a 15-la
yer long-pass edge filter in the near-infrared region designed and fab
ricated with these two thin-film materials are also reported.
