Theoretical modeling of strain-coupled nanomechanical pillar resonators

Semiconducting pillar structures have emerged as a versatile platform owing to their excellent optical performances and multiple functionalities, which enable their seamless integrations into hybrid nanodevices. The pillar cavities can be coupled to a wide variety of spin, charge, acoustic, excitonic, polaritonic, electromagnetic, or mechanical degrees of freedom as a universal building block for hybrid resonator networks. Because of the high degree of integration and reconfiguration capabilities, the strain-induced coupling may contribute to the realization of scalable photonic networks. Herein, we theoretically demonstrate control of the mechanical coupling in the resonator arrays of semiconductor monolithic pillars, and consider the practical challenges of designing high-precision and large-scale hybrid devices for single-photon source applications and advanced photonic networks. The novel dynamic features of nano-/microscale pillar resonators can be favorably implemented in mechanical functional platforms for information processing and storage.
