title = "Edge characteristic analysis of demodulation structure based on micro-ring resonator in fiber Bragg grating sensing system",
abstract = "The edge demodulation structure consisting of a micro-ring resonator and an asymmetric M-Z interferometer is proposed and investigated for applications in sensing system. According to the linear conversion between wavelength and intensity in the demodulation principle, the parameters affecting the linear region of spectral response are analyzed theoretically. Numerical analysis shows that the ratio of δ to ΔΦ is 0.5 is the best premise to realize wavelength demodulation. The accuracy decreases with the increase of coupling coefficient K, but the demodulation range is improved. The change of coupling angle k1 and k2 makes the waveform shrink according to a certain rule, thus changing the detection sensitivity. Meanwhile, the demodulation performance improves as the transmission factor α increases.",
