Abstract
This study proposes a novel fiber-optic interferometer based on the single-mode fiber-no core fiber-single mode fiber structure with the coated polydimethylsiloxane (PDMS). The no core fiber is the key carrier to excite the modal interference, and the PDMS that covers onto the fiber cascade structure is able to enhance the sensor sensitivity and also protect the sensor structure. The experimental results verify that the proposed sensor owns a high temperature sensitivity and the strain sensitivity, and it is particularly suitable for multi-parameter measurements.
