Tunable mechanical-mode coupling based on nanobeam-double optomechanical cavities
文献摘要：
Tunable coupled mechanical resonators with nonequilibrium dynamic phenomena have attracted considerable attention in quantum simulations,quantum computations,and non-Hermitian systems.In this study,we propose tunable mechanical-mode coupling based on nanobeam-double optomechanical cavities.The excited optical mode interacts with both symmetric and antisymmetric mechanical supermodes and mediates coupling at a fre-quency of approximately 4.96 GHz.The mechanical-mode coupling is tuned through both optical spring and gain effects,and the reduced coupled frequency difference in non-Hermitian parameter space is observed.These results benefit research on the microscopic mechanical parity-time symmetry for topology and on-chip high-sensitivity sensors.
