Slow light waveguide
Webbof slow light based on inducing large dispersive e• ects in optical waveguides by coupling the waveguide to an array of optical resonators. A typical device of this sort, which we … Slow light is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. Slow light occurs when a propagating pulse is substantially slowed by the interaction with the medium in which the propagation takes place. Group velocities below c were known to be possible … Visa mer When light propagates through a material, it travels slower than the vacuum speed, c. This is a change in the phase velocity of the light and is manifested in physical effects such as refraction. This reduction in speed is quantified by the … Visa mer Optical switches which make use of slow light in photonic crystals could produce faster data transmission in fiber optic cables, while having significantly lower power requirements. Slow light can also be used to control delays in optical networks, … Visa mer There are many mechanisms which can generate slow light, all of which create narrow spectral regions with high dispersion, i.e., peaks in the dispersion relation. … Visa mer The description of "luminite" in Maurice Renard's novel, Le maître de la lumière (The Master of Light, 1933), might be one of the earliest … Visa mer • Group velocities above c Visa mer
