Paper Abstract

A continuously tunable, coherence free microwave photonic filter is proposed and experimentally demonstrated. The filter is based on a high-birefringence linearly chirped fibre Bragg grating (Hi-Bi LCFBG) as the tuning component. The filter response tunability is realized through changing the differential group delay of the Hi-Bi LCFBG by applying gradient tension or adjusting the operating wavelength. Free spectral range tuning by 1.11 GHz with about 40 dB notch rejection is achieved.
