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…
Alignment-free cryogenic optical coupling to an optomechanical crystal
Timothy P. McKenna, Rishi N. Patel, Jeremy D. Witmer +3
The need for highly accurate, labor-intensive optical alignment has been a major hurdle in our ability to leverage the power of complex photonic integrated circuits. There is a str…
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…
Release-free silicon-on-insulator cavity optomechanics
Christopher J. Sarabalis, Yanni D. Dahmani, Rishi N. Patel +2
We demonstrate optically coupled nanomechanical resonators fabricated on silicon-on-insulator. Silicon fin waveguides are used to control the dispersion of mechanical waves and eng…
Efficient Photon Coupling from a Diamond Nitrogen Vacancy Centre by Integration with Silica Fibre
Rishi N. Patel, Tim Schröder, Noel Wan +4
A central goal in quantum information science is to efficiently interface photons with single optical modes for quantum networking and distributed quantum computing. Here, we intro…
