Monolithic multicore fiber based multi-parameter measurement based on spatial-division-multiplex sensing mechanisms

A monolithic all-solid multicore fiber based smart sensing system has been proposed and demonstrated in this paper. This technology enables the monitoring of multiple parameters of interest simultaneously, by spatially multiplexing specific sensing mechanisms seamlessly through different cores. The Raman distributed temperature sensor (RDTS), polarization detection based vibration sensor (PVS) and fiber Bragg grating (FBG) sensor are...
