Phonon routing in integrated optomechanical cavity-waveguide systems

Understand

The mechanical properties of light have found widespread use in the manipulation of gas-phase atoms and ions, helping create new states of matter and realize complex quantum interactions.

• The field of cavity-optomechanics strives to scale this interaction to much larger, even human-sized mechanical objects.
• Going beyond the canonical Fabry-Perot cavity with a movable mirror, here we explore a new paradigm in which multiple cavity-optomechanical elements are wired together to form optomechanical circuits.
• Using a pair of optomechanical cavities coupled together via a phonon waveguide we demonstrate a tunable delay and filter for microwave-over-optical signal processing.
