Errata: Some considerations on slow- and fast-light gyros

Incoherent "slow and fast light".

We show experimentally that the effects of pulse delay and advancement usually ascribed to the "slow and fast light" under conditions of the coherent population oscillations (CPO) can be universally observed with incoherent light fields on objects with the pure-intensity nonlinearity. As a light source, we used an incandescent lamp and as objects for study, a photochromic glass and a thermochro...

Slow and fast light: fundamentals and applications

Slow and fast light in optical fibres

The development of high-quality silica optical fibres with excellent transmission capabilities has directly contributed to the tremendous expansion of the global communication network. The success is due to their unrivalled low-loss performance (typically 50% of light is still present after a 15-km transmission distance), their wide bandwidth, which allows terabits per second of information to ...

`Slow’ and `fast’ light in resonator-coupled waveguides

We describe a device constructed of a sequence of microresonators coupled to an optical waveguide. The in ̄uence of these resonators is to enhance nonlinearities and to induce strong dispersive e€ ects, leading to exotic optical properties including slow and superluminal group velocities of propagation. In recent years there has been a ̄urry of activity aimed at the development of techniques tha...
