Abstract
Systems and methods for In-phase and Quadrature modulation. The method includes 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 generate 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 signal and generate a combined PT modulated optical signal to be transmitted towards a receiver.
