[Show abstract][Hide abstract] ABSTRACT:
A novel photonic microwave notch filter with both negative and positive coefficients is proposed and demonstrated using a single optical source. These coefficients are generated in a highly nonlinear fiber by cross polarization modulation effect and guided through a high birefringence fiber, and finally detected. Due to the orthogonal polarity between the two coefficients, the proposed filter has a stable transfer response and no resonance peaks at baseband. The experimental results showed a stable notch filter characteristic with the free spectral range of 3.97 GHz over the range of 15 GHz.
