title: Fiber-optic temperature sensing with ultrathin silicon étalons.
abstract: We report fiber-optic temperature sensing with an optically thin silicon étalon. A simple fabrication technique by direct deposition of silicon onto the fiber tip, a wide range of operating wavelengths from 1500 nm down to 800 nm, and the applicability for temperature sensing well above 400 degrees C are the most prominent features of the silicon étalon sensor.
