Paper Abstract

The dependence on polarization of the performance of a microfiber coupler based temperature sensor is experimentally investigated. The optical microfiber coupler based temperature sensor has a diameter circa 2 μm and can sense temperature in the range from 100°C to 1000°C, with an average sensitivity of 18.9 pm/°C. It is shown that different polarization states of the input signal have a significant influence on the proposed temperature sensing accuracy, with an estimated peak error of 63°C at 1000°C.
