| Abstract: | Based on the coupled mode equation,the general expressions for reflectivity and approxi-mate FWHM bandwidth of a fibre Bragg grating are deduced. We discussed the properties of phase-shifted grating and derived important results. The phase shifts of phase-shifted grating open up nar-rowband transmission windows inside the stop band of the grating,transmitted wavelength can bechanged by adjusting the amount of phase shift.The calculation and the results are given. This kind ofgrating can be used to make an all-fiber demultiplexer for multichannel lightwave systems. |
