Simultaneous Interrogation of Multiple Fiber Bragg Grating Sensors Using an Arrayed Waveguide Grating Filter Fabricated in SOI Platform

IEEE Photonics Journal, 2015
A novel fiber Bragg grating (FBG) interrogator is demonstrated based on an optimized arrayed waveguide grating (AWG) filter. The AWG response is optimized to achieve large crosstalk between the output channels, which allows simultaneous detection of ...

Nonreciprocal filtering power dividers [PDF]

, 2021
We propose the concept of nonreciprocal filtering power dividers, which are compact devices able to merge the functionalities of power dividers and combiners, the selectivity of bandpass filters, and magnetless nonreciprocity from time-modulation.
