Multiband microwave photonic filter based on chirp fiber Bragg grating

Abstract

In the proposed work, multiband reflection characteristics of CFBG have explored for different apodization. The multiband reflection bandwidth has a linear delay and phase response with respect to the operating wavelength. It is analogous to a linear time invariant system forming a microwave photonic filter with multiple pass bands. Presence of ripples in reflection and delay characteristics of CFBG is investigated with various apodization function. The proposed microwave photonic filter is useful for optical processing of light wave. Finally, the proposed MPF is used along with delay elements for the pulse shaping of optical signal. Generation of a triangular shaped waveform is proposed for different length of dispersive fiber, where dispersive element acts as a delay element.
