Escape Time Characterization of Pendular Fabry-Perot

TL;DR

This paper introduces a method to detect escape events in Fabry-Perot interferometers through reflectivity changes, enabling noise and signal analysis with minimal information loss.

Contribution

It presents a novel approach to characterize escape times in Fabry-Perot systems by measuring reflectivity changes, simplifying noise and signal detection.

Findings

Escape detection via reflectivity change is effective.

Minimal information loss occurs when only escape sequences are used.

Method can reveal noise intensity and coherent signals.

Abstract

We show that an escape from the potential minimum of Fabry-Perot interferometers can be detected measuring the associated sudden change of reflectivity. We demonstrate that the loss of information that occurs retaining only the sequence of escapes, rather than the full trajectory, can be very mild and can lead to an effective method to reveal the noise intensity or the presence of a coherent signal.
