Two-Dimensional Optomechanical Crystal Cavity with High Quantum Cooperativity
Hengjiang Ren, Matthew H. Matheny, Greg S. MacCabe +4
Optomechanical systems offer new opportunities in quantum information processing and quantum sensing. Many solid-state quantum devices operate at millikelvin temperatures -- howeve…
Ground-State Cooling of a Single Atom in a High-Bandwidth Cavity
Eduardo Uruñuela, Wolfgang Alt, Elvira Keiler +4
We report on vibrational ground-state cooling of a single neutral atom coupled to a high-bandwidth Fabry-Pérot cavity. The cooling process relies on degenerate Raman sideband trans…
Non-adiabatic Storage of Short Light Pulses in an Atom-Cavity System
Tobias Macha, Eduardo Uruñuela, Wolfgang Alt +4
We demonstrate the storage of ns light pulses in a single rubidium atom coupled to a fiber-based optical resonator. Our storage protocol addresses a regime beyond the conventio…
Design of tunable GHz-frequency optomechanical crystal resonators
Hannes Pfeifer, Taofiq Paraiso, Leyun Zang +1
We present a silicon optomechanical nanobeam design with a dynamically tunable acoustic mode at 10.2 GHz. The resonance frequency can be shifted by 90 kHz/V^2 with an on-chip capac…
