Breaking time-reversal symmetry in nano-optomechanical metamaterials
Abstract
The following seven tasks will be performed:1. Demonstrate and characterize the optomechanical nonreciprocity in a generic optomechanical whispering gallery mode resonator2. Develop a theoretical framework to connect detuning-based and momentum-biasing mechanisms for time-reversal symmetry breaking3. Realize ultrastrong optomechanical coupling in the GHz regime in a slow-light silicon waveguide4. Break time-reversal symmetry by momentum biasing5. Achieve PT-symmetry in a coupled pair of optomechanical systems6. Demonstrate low-threshold optical and acoustic lasing and invisible sensing based on PT symmetry7. Demonstrate nontrivial topological phase in compact 2D nano-optomechanical metamaterials
