Abstract: A system including a first polarization element configured to linearly polarize at least one beam in open space, a processing device configured to receive linearly polarized beams at an input, downline from the first polarization element, a first polarization switch downline from said processing device, wherein the processing device carries out an identical processing on two states of a same input beam. The processing device includes a multiple delay creation device with polarization switches, and the multiple delay creation device includes, on two routes (j=1,2): n polarization switches CPi, (1≦i≦n); n polarization splitters/recombiners SPi j (1≦i≦n); and n delay devices Rij (1≦i≦n).

Abstract: The disclosure relates to any field of application using processing that necessitates the reception of linearly polarized beams. In particular, the invention can be used in array antenna beam-shaping and aiming systems that use delay generation with polarization switching. The proposed system does not call for the use of polarization maintaining elements upline from the processing device, necessitating the reception of linearly polarized beams at input. The proposed system comprises: an element for the splitting of polarizations in open space, placed upline with respect to said processing device, said processing device itself, a polarization switch placed downline with respect to said processing device, an element for the superposing of polarization in open space, downline from said polarization switch.

Abstract: A bidirectional optical amplification system which includes an optical amplifier having an input and an output and configured to amplify wavelengths lying within a range of wavelengths and an optical coupling device. The optical coupling device includes a first port configured to receive a first optical wave in a first subrange of wavelengths lying within a range of wavelengths, a second port configured to receive a second optical wave in a second subrange of wavelengths lying within the range of wavelengths, an optical coupling output coupled to the input of the optical amplifier, and an optical coupling input coupled to the output of the optical amplifier.
