Delivering a radio frequency (RF) signal to a remote phased array antenna system involves using an optical modulator at an RF source location to modulate a high power optical carrier signal with a source RF signal Sso as to produce a high power transmit modulated optical carrier (TMOC) signal. An optical link communicates the high power TMOC signal to a remote antenna location, where the high power TMOC is split into N optical paths to obtain N reduced power TMOC signals. In each of the N optical paths, photodetection operations are performed upon the reduced power TMOC signal to obtain N reduced power S'signals which are then constructively combined to obtain a high power S&#x2032;signal which is communicated to at least one antenna element.

A wavelength converter includes an optical resonator that is optically coupled to a waveguide. The refractive index of the optical resonator is dynamically changed, such as by injecting free carriers into the resonator. This effectively changes that optical path length of the light, thus converting the wavelength.
