title: Temperature sensor based on the power reflected by a Bragg grating in a tapered fiber.
abstract: We present a temperature sensor based on two chirped gratings made in optical fibers tapered by fusion. One of the gratings has a metallic shielding and acts as sensor element, whereas the second grating provides a reference signal. The sensor is interrogated by measuring the power reflected by the two gratings, and the system has an accuracy of 0.05 degrees C over a linear operation range of more than 10 degrees C that can be adjusted in the fabrication process.
