Patent abstract
Disclosed are various embodiments of a single ended laser driving circuit. One embodiment includes a thin oxide gate switched by a data signal, the thin oxide gate configured to output a switching signal. The embodiment also includes a thick oxide current source configured to generate a bias current and a modulation current at a laser operating voltage, the modulation current based upon the switching signal, the thick oxide current source further configured to provide the bias current to the laser. The laser is configured to operate at the laser operating voltage based upon the modulation current and the bias current.
