- An apparatus for generating a broadband single-sideband signal based on a laser diode includes a first optical coupler configured to receive an optical carrier signal to divide the optical carrier signal into signals corresponding to a plurality of paths, a hybrid coupler configured to perform Hilbert transform on a radio frequency (RF) signal, a first slave laser and a second slave laser each configured to modulate optical output powers of the divided optical carrier signals by using a Hilbert-transformed RF signal, and a second optical coupler configured to receive an optical output power-modulated optical carrier signal to output a single-sideband signal.
