Numerical simulation to design single mode fiber coupler with fiber Bragg grating combination

摘要

Fiber coupler has been successfully designed and operated by combining single mode fiber and fiber Bragg grating. A characterization of fiber coupler is simulated by varying long grating of 1×10⁴ μm to 6×10⁴ μm using transfer matrix method based on coupled mode equation. The wave peak, transmission, and dispersion parameters are analyzed to determine the performance of the fiber coupler. The transmission spectrum showed the wave peaks rise to any increase in the grating length on channel 1 and channel 2. Transmission on channel 1 and channel 2 decreased from the wavelength range of 1,45 μm-1,55 μm and rised in the range of 1,55 μm-1,65 μm for each increment in length of grating. The dispersion showed the zero dispersion at specific wavelength for each increase in length of grating.
