Broadband TE(01) mode fiber coupler based on dual-core photonic crystal fiber.
A broadband TE(01) mode fiber coupler based on dual-core photonic crystal fiber (PCF) is proposed by introducing gold nanowires and fluorine-doped (F-doped) layers in the core areas. With an appropriate choice of the parameters of the F-doped layers and air hole space, the wavelength bandwidth can be increased to beyond 500 nm with the coupler length below 0.1 m for the 3 dB fiber coupler.
