Abstract:
1. A method for non-contact transmission of optical signals, the method comprising: feeding energy into an optical waveguide that is provided with an inversion material, an electron arrangement of the inversion material operable to be put into population inversion, the inversion material, by emission, emitting light with an emission wavelength such that the electron arrangement is held in a state above a thermal equilibrium and below the population inversion; beaming optical signals into the optical waveguide, the optical signals having a wavelength exciting the electron arrangement of the inversion material such that a local population inversion is created in a section of the optical waveguide; and detecting light that is created by the local population inversion effected by the inversion material in a path of the optical signals beamed in through the optical waveguide by spontaneous emission.
