【 摘 要 】

In the experimental study demonstrated the possibility of demultiplexing complex signal in the optical low mode fiber, feed beams of different wavelengths, with different polarization states with different orbital angular moments. We get a picture of the distribution of polarization possible to identify each of the beams with different wavelengths on the type of mode. Thus, analyzing the superposition of the beams on the mode composition, we can distinguish between the input signal to carry out his final demultiplexing.
