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.

Channel-dropping coupled-line filter
Electronics Letters, 1973 A novel type of channel-dropping filter, constructed in a rectangular dielectric waveguide, is described. The basis of the device is the linear frequency dependence of the coupling coefficient between two identical rods of certain dimensions. An experimental 4-channel filter in the 30–40 GHz band gives losses comparable with those of metal-waveguide ...
