  • System and method for measuring a wavelength-resolved state of polarization of an optical signal
    Patent number: 9013694
    Abstract: The present invention relates to a system and method for measuring a wavelength-resolved state of polarization, for calculating differential group delay of an optical signal under analysis (1) by means of taking multiple measurements of the spectrum of the signal under analysis (1) with spectral filtering means (3) with an optical output the power of which depends on the polarization of the input. The polarization at the input of the spectral filtering means (3) is modified by means of a polarization transformer (2) which sequentially selects a plurality of output states of polarization. The spectral filtering means (3) can comprise a filter based on stimulated Brillouin scattering amplification (10) simultaneously combining wavelength discrimination and polarization discrimination.

  • Method and device for complex analysis of optical spectrums
    Patent number: 8126326
    Abstract: This invention relates to a device and associated process capable of obtaining the optical spectrum phase of an optical signal or test signal to be analyzed using techniques for heterodyning between two monochromatic spectral components simultaneously extracted from the test signal itself by means of stimulated Brillouin scattering.
