Photothermal effect in macroscopic optomechanical systems with an intracavity nonlinear optical crystal

Sotatsu Otabe, Kentaro Komori, Ken-ichi Harada +3

Intracavity squeezing is a promising technique that may improve the sensitivity of gravitational wave detectors and cool optomechanical oscillators to the ground state. However, th…

Improving force sensitivity by amplitude measurement of light reflected from a detuned optomechanical cavity

Kentaro Komori, Takuya Kawasaki, Sotatsu Otabe +3

The measurement of weak continuous forces exerted on a mechanical oscillator is a fundamental problem in various physical experiments. It is fundamentally impeded by quantum back-a…

Reduction of quantum noise using the quantum locking with an optical spring for gravitational wave detectors

Rika Yamada, Yutaro Enomoto, Izumi Watanabe +11

In our previous research, simulation showed that a quantum locking scheme with homodyne detection in sub-cavities is effective in surpassing the quantum noise limit for Deci-hertz…
