We propose a new scheme for ultrasensitive laser gyroscopes that utilizes the physics of
exceptional points. By exploiting the properties of such non-Hermitian degeneracies, we …

Liquid crystals offer an unique versatile platform for optical applications and light
manipulation. Indeed, besides the well-known realization of liquid crystal displays, liquid …

We present an entirely linear all-optical method of cavity scale factor enhancement that
relies on mode coupling between the orthogonal polarization modes of a single optical …

The pushing of the modes of a Fabry-Perot cavity by an intracavity rubidium cell is
measured. The scale factor of the modes is increased by the anomalous dispersion and is …

Previously, we had proposed a gravitational wave detector that incorporates the white-light-
cavity (WLC) effect using a compound cavity for signal recycling (CC-SR). Here, we first use …

A passive white light cavity (WLC) based on a fiber resonator can be used for high-
bandwidth optical data buffering. Here, we report on experimental studies of such a WLC …

We investigate experimentally the lifetime of the photons in a cavity containing a medium
exhibiting strong positive dispersion. This intracavity positive dispersion is provided by a …

In this paper, we study several designs for interferometric gravitational wave detectors, and
the potential for enhancing their performance with a fast-light medium. First, we explore the …

We study theoretically a superluminal laser system comprising active and passive (lossy)
coupled micro-resonators with equal gain/loss. It is shown that when the system satisfies the …

We demonstrate superluminal light propagation using two frequency multiplexed pump
beams to produce a gain doublet in a photorefractive crystal of Ce: BaTiO_3. The two gain …
