Optomechanics in Parity-Time Symmetric Photonic Structures
Abstract
The proposed research focuses on optomechanics in non-Hermitian optical systems for the control of the interactions between optical modes (photons) and mechanical modes (phonons), and utilizes the concepts of parity-time (PT) symmetry and exceptional points (EPs) for enhancing optomechanical interactions in on-chip microresonators. The PIs will develop PT-symmetric phonon lasers and study their dynamics, demonstrate optomechanically-induced-transparency (OMIT) in PT-symmetric systems, and engineer optical systems in the vicinity of EPs or in spontaneous PT-symmetry breaking regime to enhance optomechanically-induced nonlinearity for controlling light propagation. The ultimate goal is to precisely tailor non-Hermitian optomechanical systems, via coupling strength, loss-gain balance and loss engineering, to address the challenges in optomechanics and to construct novel devices outperforming the existing ones.
