Abstract :
A hollow-core photonic bandgap fiber for optical fiber sensors is designed. According to the calculation, we get the parameters of the photonic bandgap fiber as d=0.94*2.60εm, R=Λ=2.60εm for C2H2, and d=0.94*2.41εm, R=Λ=2.41εm for CH4. Around the wavelength of λC2 H2 = 1.53εm and λCH4 = 1.66εm, 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.
