Abstract (en)
[origin: WO2005125059A1] The invention relates to a device and method for the transmission of light signals in light waveguides, comprising a laser diode as transmitter of transverse waves and a receiver, connected to the laser diode at least by means of the light waveguide, said transverse waves having an electric and magnetic field strength, a magnetic flux density, a line current density and an electric shift flux density D<i> </i> and are run from the laser diode to the receiver in the form of plane waves. According to the invention, polarisation-dependent effects, such as variable polarisation, polarisation-dependent damping and polarisation mode dispersion are to be largely avoided. The above is achieved, whereby in the transmitter a short isotropic first light waveguide (4) is connected in a parallel plane after the laser diode (2), with a dielectric constant e1, an absolute permeability ñ0 an a conductivity k 0 (relative to zero), said first light waveguide (4) having an inclined coupling at an adjustable angle F to a subsequent light waveguide (6, 6'), by means of a coupling point (5). On the receiver side, an analyser (7), for separation of the components of the electric shift flux density DZ, transmitted parallel to the longitudinal axis (19) of the receiver (3), from the total field DX,DY,DZ of the transverse wave is provided, the direction of the parallel aligned components of the electric shift flux density D<i> </i> corresponding to a particular coordinate in a fixed x,y,z- coordinate system (8).
