Fast Light, Slow Light

Optics and Photonics News, 2002
Light pulses can be made to propagate with group velocities exceeding the speed of light in a vacuum or, at the opposite extreme, to come to a complete stop.

GAP SOLITONS AND SLOW LIGHT

Journal of Nonlinear Optical Physics & Materials, 2002
Optical nonlinearity and feedback through Bragg periodicity are the basic ingredients for light localization into gap solitons. We review the basic concepts and model equations for gap solitons in Kerr and quadratic nonlinear media encompassing a one-dimensional Bragg resonance.

Slow-light solitons

Journal of Physics A: Mathematical and Theoretical, 2007
Summary: We investigate propagation of slow-light solitons in atomic media described by the nonlinear \(\Lambda\)-model. Under a physical assumption, appropriate to the slow light propagation, we reduce the \(\Lambda\)-scheme to a simplified nonlinear model, which is also relevant to 2D dilatonic gravity.

Slow-light microcavities

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
Optical microcavities with high quality factors Q are of great interest in integrated micro- and nanophotonics. Their narrow resonance and long photon lifetime (τ cav ) can be used in fundamental physics, sensing applications, microwave signal optical processing or for optical delay line and memory miniaturization [1].

Broadband dispersionless topological slow light

Optics Letters, 2020
We present a scheme to realize topological slow-light state with low group velocity and vanishing group velocity dispersion. By harnessing the strong interactions between two regular co-propagating topological photonic states in a magneto-optical photonic crystal waveguide, the energy flux transport of light exhibits a peculiar ...

Simultaneous slow and fast light

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
Simultaneous slow and fast light requires rf field [Opt. Lett. 35, 64 (2010)], which is inconvenient. We suggest that the rf field can be replaced by lights and thus, the phenomena can be realized optically.
