Near-infrared wavelengths are attenuated by the absorption of Hydroxyl ions in the medium in which this phenomenon takes place and it may be "frustrated" due to barrier penetration.
Near-infrared wavelengths are attenuated by the absorption of Hydroxyl ions in the medium in which this phenomenon takes place and it may be "frustrated" due to barrier penetration. In the early development of its principal application, it was discovered that the need for amplifiers could be eliminated by doping, which is principally done today with erbium. The Goos- Hähnchen Effect describes a small lateral shift in the wave front which affects the precise angle at which the wave was initially "pumped." Based on the respective refractive indices of the two mediums, Snell's law gives the precise angle to facilitate near infinite propagation. For 10 points-- what is this physical phenomenon employed by Fiber Optics in which light is bent back at a critical angle?
