Abstract :
A hollow-core photonic band-gap fiber for optical fiber sensors is designed. According to the calculation, we get the parameters of the photonic band-gap fiber as d=0.94*2.60μm, R=Λ=2.60μm for C2H2, and d=0.94*2.41μm, R=Λ=2.41μm for CH4. Around the wavelength of λ(C2H2) = 1.53μm and λ(CH4) = 1.66 μm, 98% of the energy is propagated in the core, the fiber is suitable to be used to detect the gas such as CH4 and C2H2.
