Temperature Sensor By Using Selectively Filled Photonic Crystal Fiber Sagnac Interferometer.

ABSTRACT

This paper reviews the application of a selectively filled photonic crystal fiber to construct sagnac interferometer (OFSI) based temperature sensor. The transmission of the OFSI is in sinusoidal form and dependent on temperature. A higher sensitivity is obtained by selective filling as compare to non selective filling, the sensitivity depends on infiltration length ratio.
