Abstract :
A reconfigurable photonic microwave bandpass filter with negative coefficients based on polarisation modulation is proposed. Experimental results show that a filter response can be reshaped by changing the polarisation state and power of optical sources corresponding to sign and amplitude of filter coefficients, respectively.
