Two separate electrooptic phase modulators are used in a modified Mach-Zehnder interferometer to vary the absolute and relative optical phases of two orthogonally polarized modes of an input signal independently of each other. A conventional Y-branch splitter on lithium niobate splits the input signal equally into the two waveguide phase modulators and an external polarization splitter recombines the two phase modulated signals in orthogonal polarization states. The polarization in the interferometer is maintained by connecting the outputs of the two phase modulators to polarization maintaining fibers. An alternate embodiment of the present invention uses an additional 3-dB directional coupler to mix the two phase modulated signals before they are combined in orthogonal polarization states.

Deux modulateurs de phase électro-optiques distincts sont utilisés dans un interféromètre de Mach-Zehnder modifié pour varier les phases optiques absolues et relatives de deux modes à polarisation orthogonale d'un signal d'entrée indépendants l'un de l'autre. Un séparateur en Y au niobate de lithium classique sépare le signal d'entrée également entre les deux modulateurs de phase à guides d'ondes, et un séparateur de polarisation externe recombine en polarisation orthogonale les deux signaux modulés en phase. La polarisation au niveau de l'interféromètre est maintenue par connexion des sorties des deux modulateurs de phase à des fibres de maintien de polarisation. Une autre version utilise un coupleur directif 3 dB pour combiner les deux signaux modulés en phase avant leur combinaison en polarisation orthogonale.
