Effects of cladding structure on the reflection spectrum of photonic crystal fiber grating
The mode field of photonic crystal fibers with regular hexagonal cladding air holes is analyzed by using RSoft.The characteristics of the Photonic Crystal Fiber Grating(PCFG) are computed and simulated by using the mode coupling theory and the transmission matrix method and the differences between the PCFG reflection spectrums with different cladding structures and fiber core sizes are compared.Simulation results show that diameter-to-pitch ratio and core sizes influence the resonance peak number and the resonant wavelengths.
