Vernier effect using in-line highly coupled multicore fibers [PDF]
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.
