    摘要: The invention relates to a method and device for controlling a physical parameter of an optical signal. According to the invention, a portion of the initial optical signal (SE) having passed through an optical waveguide from the input (24.1) to the output (24.2) thereof, is returned into said optical waveguide (24) using a sequential circulator (25) and an optical amplifier (28), in order to at least partially form the optical control signal (SE2), which counter-propagates relative to said initial optical signal (SE), so as to stabilize, or at the very least control, the physical parameter of said initial optical signal when the latter exits said optical waveguide (24) via the output (24.2) thereof.

    摘要: The present invention relates to a system (1) for stabilizing the polarization of an input light beam (2′), including a means (3) for optically guiding the input light beam (2′). In said system, the optical guide means (3) has Kerr nonlinearity and low polarization mode dispersion. Additionally, said system (1) also includes a means (4) for generating a pump light beam (4′), the polarization of which is fixed over time and the spectrum of which is suited for the Brillouin scattering threshold in the optical guide means (3). Said generating means (4) is arranged such that the input light beam (2′) and pump light beam (4′) are contra-propagating in the optical guiding means (3).
