Linewidth-broadened Fabry–Perot cavities within future gravitational wave detectors
The bandwidth of LIGO-like terrestrial interferometric gravitational wave detectors is set by the pole of the Fabry–Perot cavities within the arms of the Michelson interferometer. This constraint arises because the gain of gravitational wave-induced signal sidebands is limited to frequencies within the linewidth of the cavities. The nature of standard Fabry–Perot cavities is such that one canno...
متن کاملRealistic filter cavities for advanced gravitational wave detectors
The ongoing global effort to detect gravitational waves continues to push the limits of precision measurement while aiming to provide a new tool for understanding both astrophysics and fundamental physics. Squeezed states of light offer a proven means of increasing the sensitivity of gravitational wave detectors, potentially increasing the rate at which astrophysical sources are detected by mor...
متن کاملPreparation of Nonclassical States in Cavities with a Moving Mirror
We describe how a quantum system composed of a cavity eld interacting with a movable mirror can be utilized to generate a large variety of nonclassical states of both the cavity eld and the mirror. First we consider state preparation of the cavity eld. The system dynamics will prepare a single mode of the cavity eld in a multicomponent Schrodinger cat state, in a similar manner to that in a Ke...
متن کاملIonizing Radiation Detectors Based on Ge-Doped Optical Fibers Inserted in Resonant Cavities
The measurement of ionizing radiation (IR) is a crucial issue in different areas of interest, from environmental safety and industrial monitoring to aerospace and medicine. Optical fiber sensors have recently proven good candidates as radiation dosimeters. Here we investigate the effect of IR on germanosilicate optical fibers. A piece of Ge-doped fiber enclosed between two fiber Bragg gratings ...
متن کاملDuality relation between nonspherical mirror optical cavities and its application to gravitational-wave detectors.
In this paper, we analytically prove a unique duality relation between the eigenspectra of paraxial optical cavities with nonspherical mirrors: a one-to-one mapping between eigenmodes and eigenvalues of cavities deviating from flat mirrors by h(r) and cavities deviating from concentric mirrors by -h(r), where h need not be a small perturbation. We then illustrate its application to optical cavi...
