An integrated laser device includes a pre-distortion circuit. The
pre-distortion circuit receives an electrical modulation signal and
generates a pre-distorted modulation signal. A laser is integral with the
pre-distortion circuit. The laser includes an electrical modulation input
that is connected to the output of the pre-distortion circuit. The laser
modulates an optical signal with the pre-distorted modulation signal. The
pre-distorted modulation signal causes at least some vector cancellation
of distortion signals generated when the laser modulates the optical
signal.
