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…
Engineering phonon leakage in nanomechanical resonators
Rishi N. Patel, Christopher J. Sarabalis, Wentao Jiang +2
We propose and experimentally demonstrate a technique for coupling phonons out of an optomechanical crystal cavity. By designing a perturbation that breaks a symmetry in the elasti…
Guided acoustic and optical waves in silicon-on-insulator for Brillouin scattering and optomechanics
Christopher J. Sarabalis, Jeff T. Hill, Amir H. Safavi-Naeini
We numerically study silicon waveguides on silica showing that it is possible to simultaneously guide optical and acoustic waves in the technologically important silicon on insulat…
