An inexpensive and sensitive technique for fiber-optic sensor applications is presented. It is based on analyzing the modal power distribution in multimode optical fibers, where light propagates in a set modal pattern defined by the boundary conditions of the waveguide. In the presence of external p
## Abstract A novel method for multiplexing intensityβtype fiberβoptic sensors using wavelength division multiplexing (WDM) and spatial division multiplexing (SDM) is proposed and demonstrated. A variation of Β±0.2 dB at a loss of β10.95 dB is obtained, which is comparable with that obtained by the
