Classification: CPC H  G | IPC G  H

Claim 0:
1. A communication system comprising:
an optical signal generator configured to generate an optical local oscillator (LO) signal and an optical frequency comb that is offset in frequency from the optical LO signal;
an optical modulator configured to modulate wireless data onto the optical frequency comb;
an antenna radiating element;
a photodiode coupled to the antenna radiating element; and
an optical path configured to illuminate the photodiode with the optical LO signal and a portion of the optical frequency comb, the photodiode being configured to generate, based on the optical LO signal, the portion of the optical frequency comb, and a bias voltage applied to the photodiode, a current on the antenna radiating element that radiates wireless signals that include at least some of the wireless data.
