Acousto-optic modulation of a wavelength-scale waveguide
Christopher J. Sarabalis, Raphaël Van Laer, Rishi N. Patel +4
We demonstrate a collinear acousto-optic modulator in a suspended film of lithium niobate employing a high-confinement, wavelength-scale waveguide. By strongly confining the optica…
Acousto-optic modulation in lithium niobate on sapphire
Christopher J. Sarabalis, Timothy P. McKenna, Rishi N. Patel +2
We demonstrate acousto-optic phase modulators in X-cut lithium niobate films on sapphire, detailing the dependence of the piezoelectric and optomechanical coupling coefficients on…
Lithium Niobate Piezo-optomechanical Crystals
Wentao Jiang, Rishi N. Patel, Felix M. Mayor +6
Demonstrating a device that efficiently connects light, motion, and microwaves is an outstanding challenge in classical and quantum photonics. We make significant progress in this…
Controlling phonons and photons at the wavelength-scale: silicon photonics meets silicon phononics
Amir H. Safavi-Naeini, Dries Van Thourhout, Roel Baets +1
Radio-frequency communication systems have long used bulk- and surface-acoustic-wave devices supporting ultrasonic mechanical waves to manipulate and sense signals. These devices h…
