Abstract :
A novel photonic microwave notch filter with capability of frequency tuning is demonstrated by using S-bending based wavelength-spacing tunable dual-wavelength fibre laser. Experimental results show that the notch rejection of more than 30 dB and the flexible tunability of notch frequency in the range of 1.4-6.7 GHz.
