By mapping the signal-recycling (SR) optical configuration to a three-mirror cavity, and then to a single detuned cavity, we express the SR optomechanical dynamics, input-output relation, and noise spectral density in terms of only three characteristic parameters: the (free) optical resonant frequency and decay time of the entire interferometer, and the laser power circulating in the arm cavities. These parameters, and therefore the properties of the interferometer, are invariant under an… Expand
Converting the signal-recycling cavity into an unstable optomechanical filter to enhance the detection bandwidth of gravitational-wave detectors

Optimization of long-baseline optical interferometers for gravitational-wave detection.
The goal of this paper is to analyze and to evaluate the different configurations currently considered for the interferometric detectors of gravitational waves, and to describe the new idea of using detuned Fabry-Perot resonators, showing that, in some cases, it may represent the best compromise between bandwidth and peak sensitivity.
