Abstract[English]
Systems and methods are disclosed for In-phase and Quadrature modulation. The method comprises: i) processing In-phase digital signals and Quadrature digital signals and generating PT modulated In-phase analog signals and PT modulated Quadrature analog signals, ii) receiving an optical signal, iii) modulating the optical signal in accordance with the PT modulated In-phase analog signals and the PT modulated Quadrature analog signals and generating PT modulated In-phase optical signals and PT modulated Quadrature optical signals, iv) biasing the PT modulated In-phase optical signals and the PT modulated Quadrature optical signals to a null point, v) adjusting a phase bias point of the PT modulated Quadrature optical signals and generating phase adjusted PT modulated Quadrature optical signals, and vi) combining the PT modulated In-phase optical signals and phase adjusted PT modulated Quadrature optical signals and generating a combined PT modulated optical signal to be transmitted towards a receiver.[French]
Des systèmes et ses procédés de modulation en phase et en quadrature sont divulgués. Le procédé consiste à : i) traiter des signaux numériques en phase et des signaux numériques en quadrature et générer des signaux analogiques en phase modulés PT et des signaux analogiques en quadrature modulés PT, ii) recevoir un signal optique, iii) moduler le signal optique conformément aux signaux analogiques en phase modulés PT et aux signaux analogiques en quadrature modulés PT et générer des signaux optiques en phase modulés PT et des signaux optiques en quadrature modulés PT, iv) polariser les signaux optiques en phase modulés PT et les signaux optiques en quadrature modulés PT en un point nul, v) ajuster un point de polarisation de phase des signaux optiques en quadrature modulés PT et générer des signaux optiques en quadrature modulés PT ajustés en phase, et vi) combiner les signaux optiques en phase modulée PT et les signaux optiques en quadrature modulés PT ajustés en phase et générer un signal optique modulé PT combiné devant être transmis vers un récepteur.
