Enhancing the spectral sensitivity of interferometers using slow-light media

Abstract: Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. We demonstrate experimentally that the spectral sensitivity of an interferometer can be greatly enhanced by introducing a slow-light medium into it. The experimental results agree very well with theoretical predictions that the e… Show more

“…The large number of fringes observed in figure 4 arises from the same phe- nomenon that enhances the spectral response in a slow-light interferometer [11] (see Methods). A powerful property of the polarimetry signal is that it allows a direct read-out of the differential refractive and group indices.…”

“…In general, the phase shift, ∆φ, between two waves is produced by a differing optical path length, ∆(Ln), where n is the phase index of the wave with velocity v p = c/n, and L is the length of the path taken by the wave. The phase shift between two waves of angular frequency ω is given by [11] …”

“…In practice, it means that transformations and functions based on optical nonlinearities could be realized in much shorter distances, for instance, in 1 cm instead of 1 m if the light is slowed down to 1/10 of its normal group velocity. It has also been anticipated that the sensitivity of interferometers or sensing systems can be significantly improved by reducing the speed of the light signal [29][30][31][32][33]. However, no decisive experimental verifications have supported these predictions so far and certainly amazing and unexpected applications of this fascinating domain of slow light will be discovered in the coming years.…”

Amazing and unexpected applications of slow light will probably be discovered in the coming years through the use of innovative and creative solutions.…”
