Abstract
Based on the coupled mode theory by using the reversely recursive transmission matrix method, the switching characteristics of the λ/4 phase-shifted fiber grating and the influence of introducing chirp on the switching characteristics have been numerically studied when the reflection of the transmission facet is taken into consideration. The results show: for coherent superposition reflection strengthening, it can reduce the threshold switching energy of the λ/4 phase-shifted grating, but the switching contrast will decline; with the introduction of negative chirp in λ/4 phase-shifted grating, the switching contrast will be greatly improved, but the threshold switching energy will increase; with the introduction of positive chirp in λ/4 phase-shifted grating, the switching threshold can be further reduced, but the switching contrast will decline; and the hysteresis loop width will be influenced obviously by the introducing chirp.
