Abstract
The present invention facilitates optical modulation skew adjustment. Components of an on chip optical device driver system can cooperatively operate to provide modulated driver signals to drive configuration of optical signals. A serializer is configured to receive parallel data signals and forward corresponding serial data signals. A multiplexing component is configured to selectively output an in-phase component and a quadrature component of the serial data signals, including implementing skew adjustments to aspects of a first output signal and a second output signal. An output stage is configured to output signals that modulate an optical signal, including the first output signal and the second output signal. An on chip skew detector is configured to detect a skew difference between the first output signal and the second output signal. A skew calibration component is configured to direct skew adjustment between the first output signal and the second output signal.
