Abstract
A photonic modulator is provided that includes a transducer element that receives a RF input signal and converts the RF input signal into an elastic wave. One or more optical waveguides receive the elastic wave that has propagated a specified distance through an acoustic delay line. The one or more optical waveguides perform optomechanical transduction on the elastic wave in the presence of an optical wave, which produces one or more scattered optical waves. An optical circuit sums the one or more scattered waves to produce an optical signal output.
