Investigation of a pressure-dependent refractive index of germanium film with an optical fiber film sensor

Dongxu Yuan, Min Li, Hao Chen, Hongyun Gao
The refractive index of Ge is found in decline with applied pressure at a specific wavelength in the absorption region below 1900 nm, where the absorption coefficient rises dramatically with decreased wavelength. In this paper, we use a Ge-coated fiber optic probe to demonstrate ...
