Abstract :
A novel tunable subcarrier comb generator has been realised by dual-in-line phase modulators with optimum phase modulation indices. An optical heterodyne and microwave homodyne phaselocked loop is used to lock all optical carriers simultaneously. The hold-in range and linewidth are ~20 MHz and 20 Hz, respectively
