Cancellation of photothermally induced instability in an optical resonator
Jiayi Qin, Giovanni Guccione, Jinyong Ma +4
Optical systems are often subject to parametric instability caused by the delayed response of the optical field to the system dynamics. In some cases, parasitic photothermal effect…
Optical back-action on the photothermal relaxation rate
Jinyong Ma, Giovanni Guccione, Ruvi Lecamwasam +4
Photothermal effects can alter the response of an optical cavity, for example, by inducing self-locking behavior or unstable anomalies. The consequences of these effects are often…
Observation of Nonlinear Dynamics in an Optical Levitation System
Jinyong Ma, Jiayi Qin, Geoff T. Campbell +4
Optical levitation of mechanical oscillators has been suggested as a promising way to decouple the environmental noise and increase the mechanical quality factor. Here, we investig…
Photothermally Induced Transparency
Jinyong Ma, Jiayi Qin, Geoff T. Campbell +5
Induced transparency is a common but remarkable effect in optics. It occurs when a strong driving field is used to render an otherwise opaque material transparent. The effect is kn…
Dynamics and Stability of an Optically Levitated Mirror
Ruvi Lecamwasam, Alistair Graham, Jinyong Ma +7
We analyse the dynamics of a one-dimensional vertical Fabry-Pérot cavity, where the upper mirror levitates due to intra-cavity radiation pressure force. A perturbative approach is…
Enhanced detection of high frequency gravitational waves using optically diluted optomechanical filters
Michael Page, Jiayi Qin, James La Fontaine +2
Detections of gravitational waves (GW) in the frequency band 35 Hz to 500 Hz have led to the birth of GW astronomy. Expected signals above 500 Hz, such as the quasinormal modes of…
Linear negative dispersion with a gain doublet via optomechanical interactions
Jiayi Qin, Chunnong Zhao, Yiqiu Ma +2
Optical cavities containing a negative dispersion medium have been proposed as a means of improving the sensitivity of laser interferometric gravitational wave (GW) detectors throu…
Parametric Instability in Long Optical Cavities and Suppression by Dynamic Transverse Mode Frequency Modulation
Chunnong Zhao, Li Ju, Qi Fang +5
Three mode parametric instability has been predicted in Advanced gravitational wave detectors. Here we present the first observation of this phenomenon in a large scale suspended o…
Classical demonstration of frequency dependent noise ellipse rotation using Optomechanically Induced Transparency
Jiayi Qin, Chunnong Zhao, Yiqiu Ma +3
Cavities with extremely narrow linewidth of 10-100 Hz are required for realizing frequency dependent squeezing to enable gravitational wave detectors to surpass the free mass stand…
