FIELD: method and device for transferring information in open optical communication systems.
SUBSTANCE: method for transferring information includes spatial combination of two streams at transmitting side - supporting stream and modulated stream. For supporting stream, one polarization plane is formed, and for modulated stream, polarization plane perpendicular to first one is formed. During selection of output signal of information being transferred at receiving sides, separated are streams with mutually perpendicular polarization planes by means of spatial polarization-wise divider.
EFFECT: increased linearity spectrum of demodulation characteristic, simplification of realized device plan-wise and structure-wise.
