High frequency torsional motion transduction using optomechanical coupled oscillators
Hamidreza Kaviani, Bishnupada Behera, Ghazal Hajisalem +3
Using light to measure an object's motion is central to operating mechanical sensors that probe forces and fields. Cavity optomechanical systems embed mechanical resonators inside…
Optomechanical Detection of Light with Orbital Angular Momentum
Hamidreza Kaviani, Roohollah Ghobadi, Bishnupada Behera +5
We present an optomechanical device designed to allow optical transduction of orbital angular momentum of light. An optically induced twist imparted on the device by light is detec…
Air mode silicon nitride photonic crystals and their application to nonlinear quantum optomechanical sensing
Chris Healey, Hamidreza Kaviani, Paul E. Barclay
Nanoscale photonic crystal cavity optomechanical devices enable detection of nanomechanical phenomena with a sensitivity sufficient to observe quantum effects. Here we present the…
Towards a Room-Temperature Spin-Photon Interface based on Nitrogen-Vacancy centers and Optomechanics
Roohollah Ghobadi, Stephen Wein, Hamidreza Kaviani +2
The implementation of quantum networks involving quantum memories and photonic channels without the need for cryogenics would be a major technological breakthrough. Nitrogen-vacanc…
Design and experimental demonstration of optomechanical paddle nanocavities
Chris Healey, Hamidreza Kaviani, Marcelo Wu +4
We present the design, fabrication and initial characterization of a paddle nanocavity consisting of a suspended sub-picogram nanomechanical resonator optomechanically coupled to a…
Single crystal diamond nanobeam waveguide optomechanics
Behzad Khanaliloo, Harishankar Jayakumar, Aaron C. Hryciw +3
Optomechanical devices sensitively transduce and actuate motion of nanomechanical structures using light. Single--crystal diamond promises to improve the performance of optomechani…
Strong micro-macro entanglement from a weak cross-Kerr nonlinearity
Tian Wang, Hon Wai Lau, Hamidreza Kaviani +2
We study the entanglement generated by a weak cross-Kerr nonlinearity between two initial coherent states, one of which has an amplitude close to the single-photon level, while the…
Quantum Storage and Retrieval of Light by Sweeping the Atomic Frequency
Hamidreza Kaviani, Mohammad Khazali, Roohollah Ghobadi +3
We propose a quantum memory protocol based on dynamically changing the resonance frequency of an ensemble of two-level atoms. By sweeping the atomic frequency in an adiabatic fashi…
