Real-space characterization of cavity-coupled waveguide systems in hypersonic phononic crystals
Daiki Hatanaka, Hiroshi Yamaguchi
A phononic crystal formed in a suspended membrane provides full confinement of hypersonic waves and thus realizes a range of chip-scale manipulations. In this letter, we demonstrat…
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…
Acoustic Kerr nonlinearity of wave propagation in a planar nanoelectromechanical waveguide
Megumi Kurosu, Daiki Hatanaka, Hiroshi Yamaguchi
Nonlinearity is the key to introducing novel concepts in various technologies utilizing traveling waves. In contrast to the field of optics, where highly functional devices have be…
Modal Analysis Investigation of Mechanical Kerr Frequency Combs
Samer Houri, Daiki Hatanaka, Yaroslav M. Blanter +1
The aim of this work is to theoretically investigate the possibility of Kerr frequency combs in mechanical systems. In particular, whether microelectrome-chanical devices (MEMS) ca…
Strain-induced exciton decomposition and anisotropic lifetime modulation in a GaAs micromechanical resonator
Ryuichi Ohta, Hajime Okamoto, Takehiko Tawara +2
We demonstrate mechanical modulations of the exciton lifetime by using vibrational strain of a gallium arsenide (GaAs) resonator. The strain-induced modulations have anisotropic de…
