ABSTRACT:
A number of optical calibration systems and methods are disclosed. One optical communication system embodiment includes a number of light sources for providing a number of light beams, a number of optical paths, where each of the optical paths is positioned to receive one of the light beams, a number of optical modulators, where each modulator receives a radio frequency signal and receives one of the light beams from one of the optical paths, where each modulator modulates the light beam it receives based upon the radio frequency signal it receives to form an optical signal, and a number of optical biasing components, where each optical signal can be adjusted by at least one of the optical biasing components to calibrate the optical signals.
