Usage


In science:

The third window is around 1550 nm where the attenuation reaches an absolute minimum (Thomas et al. 2000) and where erbium doped fibers provide convenient amplifiers (Desurvire 1994). 23Chromatic dispersion in fibers is mainly due to the material, essentially silicon, but also to the refractive index profile.
Quantum Cryptography
For absorbing media it was suggested that the index of refraction should be replaced by its real part and the square of the correction factor in Eqs. (4.12) and (4.13) by the absolute square [Barnett et al. (1992, 1996); Juzeli¯unas (1997)].
