Paper Abstract

Fiber loop ringdown spectroscopy is an emerging technique, introduced in the last few years, and has demonstrated its promise in optic fiber sensor development for a variety of applications. This paper describes a new double fiber loop ringdown system, consisting of an electronic portion and two fiber loops, which can detect environmental changes in each fiber loop simultaneously. We present a theoretical simulation of the optical output of the double loop ringdown system. The simulation is modeled by the superposition of each of the individual ringdown waveforms represented by a single exponential decay and an interference term that is characterized by a Bessel function. The theoretical results are in good agreement with the experimental observations. This method may be useful for signal processing in the double fiber loop ringdown system, which is developed for simultaneous sensing in separate locations.
