Dual parametric sensors based on multi-core fiber
Date
2024
Abstract
Two optical fiber sensors based on a hole-assisted dual-core fiber (HADCF) and a hole-assisted three-core fiber (HATCF) have been proposed and experimentally demonstrated for dual-parameter measurements respectively. For the sensor based on HADCF, the dual-mode interferometer created uses the LP01 mode and LP11 mode in the suspended core, combined with a directional coupler formed by using the suspended core and the center core in a 16 mm long HADCF. For the sensor based on HATCF, two directional couplers are formed by using the suspended cores and the center core in an 8 mm long HATCF. The dual parameter measurement can be achieved through monitoring the interference dips and resonance dips. The proposed sensors have outstanding advantages such as simple structure, high integration and dual parameter measurement, making them potentially applications in the field of biological detection.
