Combined the effective mirror surface model with the transfer matrix method, a detailed theoretical and numerical study on Fabry–Perot cavity consisting of two chirped fiber Bragg gratings is investigated. Results demonstrate that transmission responses of the Fabry–Perot cavity can be adjusted by changing the cascading sequences of the two gratings. When the two gratings are connected in the direction of same chirping, approximately uniform resonance and group delay are exhibited. However, some distinctive non-uniformity of the neighboring resonance peaks intervals is shown if the two gratings are cascaded in the opposite chirping sequences. In addition, for the Fabry–Perot cavity constructed by chirped-fiber-Bragg-gratings with different amplitudes or bandwidths, efficient resonances are achieved only in the common reflection range.
► Transmission and group delay of the CFBGs-based FP cavity are analyzed. ► Influences of the gratings’ cascading sequences and parameters are studied. ► Two gratings connected in the same chirping sequences are simulated. ► Two gratings connected in the opposite chirping sequences are simulated. ► Two gratings with different amplitudes or bandwidths are analyzed.
