Slow photon effect

Slow light effects are not due to abnormally large refractive indices, as will be explained below. The simplest picture of light given by classical physics is of a wave or disturbance in the electromagnetic field. In a vacuum, Maxwell's equations predict that these disturbances will travel at a specific speed, denoted by … Visa mer 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 … Visa mer Optical switches which make use of slow light in photonic crystals could produce faster data transmission in fiber optic cables, while having … 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 When light propagates through a material, it travels slower than the vacuum speed, c.
