Apparatus and method of generating broadband single-sideband signal based on laser diode

A method of generating a broadband single-sideband signal based on a laser diode, the method comprising:

• receiving an optical carrier signal and a radio frequency (RF) signal;
• dividing, by a first optical coupler, the optical carrier signal into signals corresponding to a plurality of paths;
• inputting the divided optical carrier signals to a plurality of slave lasers corresponding to the plurality of paths;
• inputting the RF signal to the plurality of slave lasers via a hybrid coupler;
• modulating, by the plurality of slave lasers, optical output powers of the divided optical carrier signals using the RF signal;
• and
• receiving, by a second optical coupler, the optical output power-modulated optical carrier signals to output a broadband single-sideband signal.
