Abstract: We report all-optical regeneration of the state of polarization of a 40 Gbit/s return-to-zero telecommunication signal. The device discussed here consists of a 6.2-km-long nonzero dispersion-shifted fiber, with low polarization mode dispersion, pumped from the output end by a backward propagating wave coming from either an external continuous source or a reflection of the signal. An initially scrambled signal acquires a degree of polarization close to 100% toward the polarization generator output. All-optical regeneration is confirmed by means of polarization and bit-error-rate measurements as well as real-time observation of the eye diagrams. We show that the physical mechanism underlying the observed four-wave-mixing-based polarization attraction phenomenon can be described in terms of the geometric approach developed for the study of Hamiltonian singularities.

Maggiori informazioni: We acknowledge the insightful contribution to the theoretical description of polarization attraction of Victor V. Kozlov, who unfortunately could not see the completion of this work because of his decease. We will remain grateful to Victor for the many discussions we shared and his enthusiasm. All the experiments were performed on the PICASSO platform in ICB. We acknowledge financial support from the European Research Council under the Grant Agreement 306633 PETAL ERC project, the CNRS, the Labex ACTION program (contract ANR-11-LABX-01-01), and the Conseil Regional de Bourgogne under the PHOTCOM program.Parole chiavi: Bit error rate; Dispersion (waves); Four wave mixing; Nonlinear optics; Optical communication; Optical fiber communication; Polarization; Polarization mode dispersion, Backward propagating waves; Bit error rate measurements; Fiber optics and optical communications; Non-zero dispersion shifted fiber; Nonlinear optical devices; Nonlinear optics , fibers; Optical processing; Telecommunication signals, Optical signal processingDOI: 10.1364/PRJ.1.000115Citazioni: 2dati da “WEB OF SCIENCE” (of Thomson Reuters) aggiornati al: 2022-08-14Riferimenti tratti da Isi Web of Knowledge: (solo abbonati) Link per visualizzare la scheda su IsiWeb: Clicca quiLink per visualizzare la citazioni su IsiWeb: Clicca qui
