Abstract: We propose a compact microbend sensor operating in the reflection mode for simultaneous measurement of a mechanical parameter and the temperature. The sensor is composed of a single-mode fiber lead, a multimode sensing fiber, and a single-mode fiber Bragg grating, where microbending is applied to the multimode fiber for mechanical parameter measurement and the grating provides an additional signal for temperature measurement. The sensor is demonstrated experimentally with two demodulation schemes based on a broad-band source and a tunable laser, respectively. The sensor extends the capacity of a conventional microbend sensor and offers many additional advantages, including higher stability, higher sensitivity, single-end access, and superior multiplexing capability.
