<p>A method and a device for optical data transmission are proposed. Incoming optical signals having respective incoming waveguide modes are mapped into outgoing optical signals having respective outgoing waveguide modes, using optical spatial modulators, whose multiplicative patterns correspond to the respective electrical field patterns of the respective incoming or outgoing waveguide modes. An incoming optical signal, whose respective incoming waveguide mode is of an azimuthal order equal to zero, results in an outgoing optical signal, whose respective outgoing waveguide mode is of an azimuthal order equal to zero. Furthermore, two incoming optical signals, whose respective second incoming waveguide modes are of a same azimuthal order greater than zero,of a same radial order, and orthogonal to each other result in respective outgoing signals, whose respective outgoing waveguide modes are off a same azimuthal order greater than zero,of a same radial order and orthogonal to each other.</p> |
