Discrimination between refractive index and temperature by two cascaded cladding-mode type fiber sensors
We demonstrated a fiber sensor for simultaneous measurement of refractive index and temperature by cascading one long period grating and one modal interferometer. Cladding mode interference between them was also ...
Temperature sensor by using selectively filled photonic crystal fiber Sagnac interferometer
In this paper, we report an optical fiber Sagnac interferometer (OFSI)-based temperature sensor constructed by a selectively filled polarization-maintaining photonic crystal fiber (PM-PCF). The transmission spectrum of the ...
Sagnac interferometer based temperature sensor by using selectively filled photonic crystal fiber
A Sagnac interferometer based temperature sensor is proposed by using a piece of selectively filled polarization maintaining photonic crystal fiber. The sensitivity dependence on the infiltration length ratio was studied ...
