Improving the optomechanical entanglement and cooling by photothermal force

M Abdi, AR Bahrampour - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
Cooling and entanglement in optomechanical systems coupled through radiation pressure
and photothermal force are studied. To develop the photothermal model, we derive an …

Competition between heating and cooling effects in an optomechanical oscillator using a squeezed field

VNT Pham, CM Hoang, ND Vy - Journal of Modern Optics, 2021 - Taylor & Francis
Squeezed light is a useful phenomenon that can be exploited to improve the sensitivity of
specific classes of detectors based on optomechanical effects. In this study, the effect of …

Analysis of chaotic behavior in an optical microresonator

M Vahedi, AR Bahrampour, HR Safari - Optics Communications, 2014 - Elsevier
In this paper, for the first time, chaotic behavior of a classical moving-mirror Fabry–Perot
cavity is obtained by finding numerical solution of a system of delay differential equations …
