Near-field cavity optomechanical coupling in a compound semiconductor nanowire
Motoki Asano, Guoqiang Zhang, Takehiko Tawara +2
A III-V compound semiconductor nanowire is an attractive material for a novel hybrid quantum interface that interconnects photons, electrons, and phonons through a wavelength-tunab…
Multimode internal resonances in a MEMS self-sustained oscillator
S. Houri, D. Hatanaka, M. Asano +1
We investigate the dynamics of a microelectromechanical (MEMS) self-sustained oscillator supporting multiple resonating and interacting modes. In particular, the interaction of the…
Optically probing Schwinger angular momenta in a micromechanical resonator
Motoki Asano, Ryuichi Ohta, Takuma Aihara +3
We report an observation of phononic Schwinger angular momenta, which fully represent twomode states in a micromechanical resonator. This observation is based on simultaneous optic…
Limit cycles and bifurcations in a nonlinear MEMS oscillator with a 1:3 internal resonance. Part I: The case of a driven resonator
S. Houri, D. Hatanaka, M. Asano +2
This work investigates the behavior of an AlGaAs/GaAs piezoelectric nonlinear MEMS oscillator exhibiting a 1:3 internal resonance. The device is explored in an open-loop configurat…
Pulse-width modulated oscillations in a nonlinear resonator under two-tone driving as a means for MEMS sensor readout
Samer Houri, Ryuichi Ohta, Motoki Asano +2
A MEMS Duffing resonator is driven by two adjacent frequency tones into the nonlinear regime. We show that if the two-tone drive is applied at a frequency where a bistable response…
Active control of a plasmonic metamaterial for quantum state engineering
S. A. Uriri, T. Tashima, X. Zhang +7
We experimentally demonstrate the active control of a plasmonic metamaterial operating in the quantum regime. A two-dimensional metamaterial consisting of unit cells made from gold…
