We present the theory and experimental realization of simultaneously localized and strongly coupled optical and mechanical modes in periodic nanostructures. The mechanical properties of localized phonons with Gigahertz frequencies and sub-picogram masses are studied via all-optical measurements.
A new cavity-optomechanical system has been developed comprised of two doubly-clamped silicon nitride cantilevers with a 1D photonic crystal etched into them. We will discuss the optical properties of the system and potential applications to solid-state cavity QED with diamond color centers.
A bottom-up approach based on template-directed colloidal self-assembly was used for fabricating metal nanocluster based matematerials and their optical properties were studied experimentally. Negative index material composed of nanoclusters and metal wires was numerically demonstrated.
We report nanophotonic energy up-conversion operation in ZnO nanorod double-quantum-well structures assisted by the optical absorption of phonons via an optical near-field.
