The applications range from acoustic filters for mobile handsets to quantum information science./However, up to date, the interaction between harmonic modes of surface acoustic waves (SAWs) and photons has not been studied in detail. Here, we develop radio frequency (RF)-modulated light emitters driven by the coupling between electrical and acoustic signals at room temperature. The light emitter demonstrates a 990-MHz oscillation behavior which cannot be solely achieved by electrical driving due to resistance-capacitance (RC) limit. Instead, the result is attributed to the excitation by the harmonics of SAWs in the light emitter. The gigahertz light oscillation enables a new architecture for information processing. In this work, we also demonstrate the coupling between acoustooptical and electrooptical interactions by simultaneously applying 990-MHz acoustic signals and 20-MHz modulated electrical inputs. ? 1986-2012 IEEE.Acoustic surface wave devices; Harmonic analysis; Light; Light emission; Photons; Sawing; Electrical driving; High order harmonics; Optical oscillations; Oscillation behavior; Quantum information science; Radio frequencies; Resistance capacitance; Surface acoustic waves; Acoustic waves; article; excitation; oscillation; radiofrequency; room temperaturejournal article10.1109/TUFFC.2020.3010269327462122-s2.0-85101987502
