Abstract:
The present invention is directed to optical communication systems and methods thereof. In various embodiments, the present invention provides method for linearizing Mach Zehnder modulators by digital pre-compensation and adjusting the gain of the driver and/or the modulation index. The pre-compensation can be implemented as a digital pre-compensation algorithm, which is a part of an adaptive feedback loop. There are other embodiments as well.

Claim (Index 10):
A method for modulating signals for an communication system, the method comprising:\n performing nonlinear mapping a modulation signal using a first modulation index to generate a voltage signal using an inverse transformation function and an adjustable modulation index value; processing the voltage signal using a linear equation; converting the processed voltage signal to an analog signal; generating a driving signal based on the analog signal; measuring a peak voltage of the driving signal in a transmitter; performing MZ modulation on the driving signal to generate an output signal; determining a ratio between a DC power and a second order harmonic values of measured output power; determining a second modulation index based at least on the driving signal and the first modulation index; modifying the adjustable modulation index value using the second modulation index and the ratio; and transferring data.
