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…
Modeling Dispersive Coupling and Losses of Localized Optical and Mechanical Modes in Optomechanical Crystals
Matt Eichenfield, Jasper Chan, Amir H. Safavi-Naeini +2
Periodically structured materials can sustain both optical and mechanical excitations which are tailored by the geometry. Here we analyze the properties of dispersively coupled pla…
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…
Static and dynamic wavelength routing via the gradient optical force
Jessie Rosenberg, Qiang Lin, Kerry J. Vahala +1
Here we propose and demonstrate an all-optical wavelength-routing approach which uses a tuning mechanism based upon the optical gradient force in a specially-designed nano-optomech…
Mechanical oscillation and cooling actuated by the optical gradient force
Qiang Lin, Jessie Rosenberg, Xiaoshun Jiang +2
In this work we combine the large per-photon optical gradient force with the sensitive feedback of a high quality factor whispering-gallery microcavity. The cavity geometry, consis…
