Vernier effect using in-line highly coupled multicore fibers

Scientific Reports, 2021
We demonstrate optical fiber sensors based on highly coupled multicore fibers operating with the optical Vernier effect. The sensors are constructed using a simple device incorporating single-mode fibers (SMFs) and a segment of a multicore fiber.

Controlled Excitation of Supermodes in a Multicore Fiber with a 5 × 5 Square Array of Strongly Coupled Cores

Photonics, 2021
Coherent propagation of supermodes in a multicore fiber is promising for power scaling of fiber laser systems, eliminating the need for the active feedback system to maintain the phases between the channels. We studied the propagation of broadband pulsed

Spatially and spectrally resolved multicore optical fiber sensor with polarization sensitivity

AIP Advances, 2022
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

A Novel Fiber Optic Sensor for Microparticle Velocity Measurement Using Multicore Fiber

Applied Sciences, 2020
A novel fiber optic sensor is proposed to achieve the measurement of single microparticle velocity in a two-dimensional space by translating the cores of a multicore fiber in their respective directions into independent spatial filters.
