An acousto-optical waveguide device with compensation of polarization mode dispersion (PMD) comprises at least one first and one second optical path in optical waveguide and at least one compensation optical path connected to the first and second optical path; the compensation optical path has a prefixed PMD such that the passage time of a first polarization component of an optical signal in the first optical path and in the compensation optical path is substantially equal to the passage time of a second polarization component in the second optical path and in the compensation optical path.
L'invention est un guide d'ondes acousto-optique à correction de la dispersion de polarisation comportant au moins un premier et un second trajets optiques dans le guide de lumière et au moins un trajet de correction optique connecté à ce premier et à ce second trajets optiques. Le trajet de correction optique a une dispersion de polarisation préfixée de telle façon que le temps de passage d'une première composante polarisée d'un signal lumineux dans le trajet optique et dans le trajet de correction optique est substantiellement égal au temps de passage de la seconde composante polarisée dans le second trajet optique et dans le trajet de correction optique.
