Simulasi Fiber Coupler Kombinasi Serat Moda Tunggal Dan Serat Kisi Bragg Untuk Komponen Sensor Optik
Fiber coupler was successfully developed by combining single mode fiber and fiber Bragg grating. A characterization of fiber coupler was analyzed based on result simulation by using OptiGrating software with varying long gratings of 1×104????????????????, 2×104???????????? , 3×104????????????????, 4×104????????????????, 5×104????????????????, and 6×104???????????????? using transfer matrix method based on coupled mode equation. The wave peak, transmission, and dispersion were parametrics that are analyzed to determine the performance of fiber coupler. The transmission spectrum showed that the increasing wave peak for each longer grating on channel 1 and channel 2, transmisitivity on channel 1 and channel 2 decreasing of wavelength range of 1,45 ????????????????−1,55 ???????????????? and raise back in the range of 1,55 ????????????????−1,65 ???????????????? for each increase long grating. On channel 1, the highest dispersion value being on wavelength 1,48 ???????????????? on varying long grating 3×104????????????????. On channel 2, the most dispersion value obtained on varying long grating 6×104????????????????.
