Abstract
A direct-drive modulator driver and an optical transponder including the driver are disclosed. The driver includes a transistor having a first terminal, a second terminal and an input terminal, where said first terminal is grounded. The driver further comprises of a laser diode having a p-terminal and an n-terminal, where said p-terminal is coupled to a power supply, and said n-terminal is coupled to the second terminal of the transistor. The driver further comprises of an input load coupled to the input terminal of the transistor.
