We design and fabricate a multicore fiber sensor with the end facets of cores patterned with one-dimensional sub-wavelength Au wire grid polarizers, which are aligned either radially or azimuthally on the cross section of the fiber.

Abstract: We design and fabricate a multicore fiber sensor with the end facets of cores patterned with one-dimensional sub-wavelength Au wire grid polarizers, which are aligned either radially or azimuthally on the cross section of the fiber. With a fan-out device bridging the individual cores and external single core fibers followed by a compact spectrometer, it is able to spatially detect the light intensity, spectrum, and polarization states of the incident light in a highly integrated format. These multicore fiber sensors offer a new opportunity to simultaneously measure multiple optical parameters by a single operation.
