LASER DRIVER FOR DRIVING LASER DIODE
First Claim
1. A laser driver to provide a shunt current to a laser diode, comprising:
- a first generator to generate a first signal in response to an input signal, the first signal having first amplitude and a first rising transition that switches the laser diode from an ON state to an OFF state;
a second signal generator to generate a second signal in response to the input signal, the second signal having second amplitude smaller than the first amplitude and a second rising transition having a delay from the first rising transition; and
an output terminal configured to output the shunt current to an anode of the laser diode, the shunt current including the first signal and the second signal.

Abstract
A laser driver to provide a shunt current to a laser diode is disclosed. The laser driver includes a first generator to generate a first signal in response to an input signal and a second signal generator to generate a second signal in response to the input signal. The first signal has first amplitude and a first rising transition that switches the laser diode from an ON state to an OFF state of the laser diode. The second signal has second amplitude smaller than the first amplitude and a second rising transition having a delay from the first rising transition. The laser driver further includes an output terminal to output the shunt current including the first signal and the second signal.
