Abstract
Various embodiments of an optical transmitter and a method of operating an optical transmitter are disclosed. In one embodiment, the optical transmitter includes a laser and a laser driver configured to drive the laser using either a voltage driving topology (CDT) or a current-driving topology (VDT). The laser driver includes a switch that is configured to switch between the CDT and the CDT based on an operating frequency of the optical transmitter.
