Few-mode fiber based optical sensors
Optics Express, 2015 Few-mode fibers (FMFs) have found applications in optical communications and sensors with attractive features that standard single mode fiber (SSMF) do not possess. We report our recent progress on FMF based optical sensors, and show the potential of utilizing the spatial dimension for multi-parameter sensing with discrimination capability.

Rayleigh scattering in few-mode optical fibers [PDF]
Scientific Reports, 2016 AbstractThe extremely low loss of silica fibers has enabled the telecommunication revolution, but single-mode fiber-optic communication systems have been driven to their capacity limits. As a means to overcome this capacity crunch, space-division multiplexing (SDM) using few-mode fibers (FMF) has been proposed and demonstrated.

Demonstration of Mode-Evolutional Multiplexer for Few-Mode Fibers Using Stacked Polymer Waveguide
IEEE Photonics Journal, 2015 Mode-evolutional multi/demultiplexer for few-mode fibers was demonstrated using stacked polymer waveguides. Owing to the stacked structure, TE00, TE10, and TE01 modes, which correspond to LP01, LPeven11 , and LPodd 11 modes, respectively, were ...
