Abstract
An electronic device may include a receiver having a light source that provides an optical signal to an optical splitter. An optical combiner may be coupled to the optical splitter over a set of parallel optical paths. A phased antenna array may have a set of antennas disposed on the optical paths. Each antenna may include an optical modulator disposed on a respective one of the optical paths and an antenna resonating element coupled to the modulator. Incident radio-frequency signals may produce electrical signals on the antenna resonating elements. Optical phase shifters may provide optical phase shifts to the optical signal. The modulators may modulate the optical local oscillator signal using the electrical signals. The optical combiner may generate a combined signal by combining modulated optical signals from the optical paths. A demodulator may recover wireless data from the radio-frequency signals using the combined signal.
