Fast-light for astrophysics: super-sensitive gyroscopes and gravitational wave detectors
TLDR
In this article, the authors present a theoretical analysis and experimental study of the behavior of optical cavities filled with slow and fast light materials, and show that the fast-light material-filled cavities have properties useful for astrophysical applications such as enhancing the sensitivity-bandwidth product of gravitational wave detection and terrestrial measurement of Lense-Thirring rotation via precision gyroscopy.Abstract:
We present a theoretical analysis and experimental study of the behaviour of optical cavities filled with slow- and fast-light materials, and show that the fast-light material-filled cavities, which can function as ‘white light cavities’, have properties useful for astrophysical applications such as enhancing the sensitivity-bandwidth product of gravitational wave detection and terrestrial measurement of Lense–Thirring rotation via precision gyroscopy.read more

TL;DR: In this paper, the authors proposed a new scheme for ultra-sensitive laser gyroscopes that utilizes the physics of exceptional points and showed that the rotation-induced frequency splitting becomes proportional to the square root of the gyration speed, thus enhancing the sensitivity to low angular rotations by orders of magnitudes.

Laser gyro at quantum limit
TL;DR: In this article, it was shown that a certain fundamental limit applies to the accuracy of all optical rotation sensors which use laser light as a probe, and the same relationship is obtained from a spontaneous-emission noise formulation.

Tutorials in Complex Photonic Media
TL;DR: Alekseyev et al. as mentioned in this paper proposed negative phase velocity propagation using a square wire array and showed that the wire array's plasma frequency and damping rate is a function of the number of wires in the array.

Application of fast-light in gravitational wave detection with interferometers and resonators
M. S. Shahriar,M. Salit +1 more
TL;DR: In this article, a modified version of the Sagnac interferometer is replaced by a zero-area ring resonator fed by an external laser, and the effect of such a medium on designs similar to those already planned for Advanced LIGO is explored.

Fast-light in a photorefractive crystal for gravitational wave detection
TL;DR: How anomalous dispersion produced this way in a faster photorefractive crystal (such as SPS: Sn(2)P( 2)S(6)) could be employed to enhance the sensitivity-bandwidth product of a LIGO type gravitational wave detector augmented by a White Light Cavity is discussed.

Gain-assisted superluminal light propagation
TL;DR: Gain-assisted linear anomalous dispersion is used to demonstrate superluminal light propagation in atomic caesium gas and is observed to be a direct consequence of classical interference between its different frequency components in an anomalously dispersion region.

TL;DR: The dispersive properties of the atomic transition in the rubidium line are measured and this ladder-type system is observed to exhibit electromagnetically induced transparency together with a rapidly varying refractive index.

Recycling in laser-interferometric gravitational-wave detectors.
TL;DR: It is shown that it may be made to further enhance the sensitivity within a narrow bandwidth, becoming tuned recycling, and the various sensitivity-bandwidth combinations, together with the tuning properties, are discussed.
