Abstract
We demonstrate a temperature sensor with ~ 9 times sensitivity enhancement that consists of two cascaded sagnac interferometers and works analogously to a Vernier scale. Experimental results show that the temperature sensitivity is increased from -1.46 nm/°C based on a single sagnac configuration to -13.36nm/°C.
