Abstract
A driver circuit for an optical transmitter includes a main path in parallel with an inverting path. The data signals from the main path and the inverting path can be combined to generate an output signal for a laser diode. The main path can communicate a data signal via a first transmission line and the inverting path can communicate an inverted data signal via a second transmission line. The second transmission line can be longer than the first transmission line in order to delay the inverted data signal. In addition, the inverted data signal can be weighted before being combined with the data signal from the main path.
