Towards New Regimes in Cavity Optomechanics with Photonic Bound States in the Continuum in Photonic Crystal Membranes

Paper i proceeding, 2022

We will present an optomechanics platform based on photonic bound states in the continuum and show that this platform is very flexible and makes it possible to reach different regimes of cavity optomechanics, e.g., with linear or quadratic coupling of either dispersive or dissipative type. Bound states in the continuum enable to build compact optomechanical devices, resulting in linear optomechanical coupling strengths that are orders of magnitude larger than conventional out-of-plane systems and comparable to values observed for in-plane geometries.
