Coherent Coupling between Different Mechanical Modes

ORAL

Abstract

Optomechanical devices have been constructed at many different scales and frequencies. A hybrid system which capitalizes on the advantages of distinct mechanical modes is useful for both quantum information and tests of fundamental physics. We demonstrate this capability with two mechanical resonators: a Si3N4 membrane trampoline and a suspended DBR mirror. We will discuss how we coherently transfer the state of one resonator to the other nondegenerate resonator with two laser tones. We will also discuss a mechanical-optical-mechanical analog to STIRAP for multimode mechanical state transfer. This technique should enable high efficiency state transfer between higher order mechanical modes even in the presence of mechanical and optical losses.
