摘要
PURPOSE: A photonic microwave notch filter is provided to easily control notch frequency by controlling the lattice intervals of a brag grating and to uniformly maintain a center wavelength.;CONSTITUTION: A photonic microwave notch filter comprises a delay controller(100). The delay controller comprises a ring plate(110), a fixing pivot(130), a moving pivot(150), and an optical fiber(170). The fixing pivot is fixed to the ring plate. The moving pivot is moved along the ring plate. The optical fiber is fixed to the fixing pivot and the moving pivot and reflects light through a brag grating.;COPYRIGHT KIPO 2010
