We propose and demonstrate experimentally the strong dissipative acousto-optic interaction between a suspended vibrating microfiber whispering-gallery microcavity. On one hand, response driven by an external stimulus of acoustic waves is found to be stronger than dispersive 2 orders magnitude. other dead points emerge with zero at certain parameters, promising potentials in physical sensing such as precise measurements magnetic field temperature. The then explored for ultrasensitive...
In this paper, we have measured the magneto-optical spin Hall effect influenced by an arbitrary oriented magnetic field using CeDyAl thin films on Gd3Ga5O12 (GGG) substrates as reflective materials. Plots of variation magneto-optic (MOPSHE) with strength, hysteresis line, in three different unit-direction fields are simulated and experimentally measured. The comparison simulation results experiments allows method weak measurement to determine MOPSHE under influence be validated. a...
We study an ultrasound sensor using the dissipative interaction in optical microcavity-microfiber coupling system. The sensitivity of this microcavity is demonstrated to be insensitive Q factors.
We construct a strong dissipative acousto-optic interaction in whispering-gallery-mode microcavity and suspended microfiber. The response presents an improvement by two orders of magnitude compared with the dispersive acoustic response. Moreover, dead points zero responses appear under certain parameters. This is applied ultrasensitive ultrasound detection, which proved to be insensitive quality factors.
