Abstract :
A novel all optical single side-band signal generation filter using optically phase shift scheme with fiber Bragg grating based 4-taps optical Hilbert transformer is experimentally demonstrated. The sideband suppression ratio above 10 dB shows the feasibility of the optically phase-shifted SSB scheme which is applicable for high-speed transmission with bandwidth efficiency.
