Modulation of stimulated emission of ZnO nanowire based on electromechanical vibration

An optical modulator is proposed using a double-clamped nanoelectromechanical resonator. Electromechanical–optical analysis has been performed to validate the idea. The electromechanical simulation involves the nonlocal effect as the resonator is in nanometer scale. Stimulated emission theory has been used to model the luminescence of the nanowire due to the addition of piezoelectric charges subjected to mechanical strains. Results successfully demonstrate both the intensity modulation and frequency filtering, providing an integrated solution in applications such as quantum entanglement experiments
