Abstract :
A novel structure of microwave photonic filter (MPF) is proposed based on the phase-shifted fiber Bragg grating (PS-FBG). It can realize single pass band scheme. And if we add an optical fiber delay line, we can realize high Q performance by adjusting the reflectivity of two FBGs. We can also achieve tunability by adjusting the optical carrier frequency.
