Nanophotonic optomechanical sensing

Abstract

Nanoscale photonic devices can be engineered to enable strong interaction between mechanical resonances and co-located optical fields. This interaction can be harnessed for sensitive displacement measurement, force sensing, and more recently, torque sensing. Using photonic crystal split beam and slot mode cavities, we have demonstrated detection of torsional motion at frequencies spanning MHz to nearly a GHz. In this talk we will show how this sensitive detection allows probing of the dynamics of nanoscale magnetic structures, opening new avenues for experiments in condensed matter physics.
