Coherent mixing of mechanical excitations in nano-optomechanical structures
Qiang Lin, Jessie Rosenberg, Darrick Chang +4
The combination of large per-photon optical force and small motional mass attainable in nanocavity optomechanical systems results in strong dynamical back-action between mechanical…
Characterization of radiation pressure and thermal effects in a nanoscale optomechanical cavity
Ryan M. Camacho, Jasper Chan, Matt Eichenfield +1
Optical forces in guided-wave nanostructures have recently been proposed as an effective means of mechanically actuating and tuning optical components. In this work, we study the p…
Optomechanical Crystals
Matt Eichenfield, Jasper Chan, Ryan M. Camacho +2
Structured, periodic optical materials can be used to form photonic crystals capable of dispersing, routing, and trapping light. A similar phenomena in periodic elastic structures…
Optical and mechanical design of a "zipper" photonic crystal optomechanical cavity
Jasper Chan, Matt Eichenfield, Ryan Camacho +1
Design of a doubly-clamped beam structure capable of localizing mechanical and optical energy at the nanoscale is presented. The optical design is based upon photonic crystal conce…
A picogram and nanometer scale photonic crystal opto-mechanical cavity
M. Eichenfield, R. Camacho, J. Chan +2
We describe the design, fabrication, and measurement of a cavity opto-mechanical system consisting of two nanobeams of silicon nitride in the near-field of each other, forming a so…
Wide-bandwidth, tunable, multiple-pulse-width optical delays using slow light in cesium vapor
Ryan M. Camacho, Michael V. Pack, John C. Howell +2
We demonstrate an all-optical delay line in hot cesium vapor that tunably delays 275 ps input pulses up to 6.8 ns and 740 input ps pulses up to 59 ns (group index of approximately…
