Arsenic Selenide (CAS 1303-36-2) is an inorganic chemical compound, a selenide of arsenic. Amorphous arsenic triselenide is used as a chalcogenide glass for infrared optics. When purified, it transmits light with wavelengths between ca. 0.7 and 19 µm. Arsenic Selenide is covalently bonded. Even so, the arsenic has a formal oxidation state of +3.

Arsenic Selenide (CAS 1303-36-2) is of interest for use in dielectric meta-surfaces. It has a high linear refractive index, n=2.8, enabling high index contrast with its surrounding medium. It has an exceptionally high optical nonlinearity (n2 < 900 × that of silica) making it a good candidate for nonlinear metasurfaces.
Besides, its bandgap of 1.8 eV and wide transmission window, spanning from approximately 1.5-14 μm, makes it useful for applications in the shortwave infrared into the long-wave infrared.[1]
