Abstract
A beamforming element comprises an imprinting-shifting component configured to imprint an input signal onto a second beam to form an imprinted beam and adjust the optical phase of the imprinted beam; one or more multi-beam optical couplers configured to receive a phase-shifted imprinted beam and a first beam and form an interference beam from the combination thereof; and one or more optical-to-electrical converter components configured to receive an interference beam and generate an electrical signal based thereon that includes the beamforming time delay(s) and is frequency up/down-converted with respect to the input signal.
