The device of optical phase conjugation, and apparatus for transmission and reception optics intended to be used with a system of optical telecommunications using the device of optical phase conjugation

摘要

The invention relates to a device for the combination of optical phase can be used with a repeater, for example, in a system of optical telecommunications over very long distances, as well as with a receiving apparatus and an apparatus for the optical emission. The device of the assembly comprises a section (1) of the combination of optical phase serving to deliver a light signal whose frequency is the inverse of that of the light signal which is applied to it, and a section (2) of conversion of the frequency used to deliver a light signal whose frequency is converted from that of the light signal which is applied to it from the section (1) of the optical phase conjugation. It combines a certain number of times the cross section of the assembly (1) and the cross-section of conversion (2) so that the frequency of the light signal output of the device of the phase conjugation, coincides with the frequency of the light signal which is applied to it.
