Abstract:
A method and apparatus for characterizing and compensating optical impairments in an optical transmitter includes operating an optical transmitter comprising a first and second parent MZ, each comprising a plurality of child MZ modulators that are biased at respective initial operating points. An electro-optic RF transfer function is generated for each of the plurality of child MZ modulators. Curve fitting parameters are determined for each of the plurality of electro-optic RF transfer functions and operating points of each child MZ modulator are determined using the curve fitting parameters. An IQ power imbalance is determined using the curve fitting parameters. Initial RF drive power levels are determined that compensate for the determined IQ power imbalance. The XY power imbalance is determined for initial RF drive power levels using the curve fitting parameters. The operating RF drive powers are determined that at least partially compensate for the first and second IQ power imbalances and for the XY power imbalance for the optical transmitter. An optical signal comprising a Nyquist-pulse-shape is generated at an output of the optical transmitter.

Claim (Index 31):
The method of characterizing and compensating of  claim 23  wherein the biasing the first and second child MZ modulators of the X-Pol. IQ and the Y-Pol. IQ modulators at the initial operating point comprises biasing the first and second child MZ modulators of the X-Pol. IQ and the Y-Pol. IQ modulators at bias points that results in an optical output power that is less than \u221245 dBm.
