Abstract
Official abstract text for this publication.
An arbitrary waveform generator modifies the input signal to a laser diode driver circuit in order to reduce the overshoot/undershoot and provide a “flat-top” signal to the laser diode driver circuit. The input signal is modified based on the original received signal and the feedback from the laser diode by measuring the actual current flowing in the laser diode after the original signal is applied to the laser diode.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: receiving, by a control circuit, a digital description of a current pulse, the digital description including information about a current value and a duration for which the current value is to be applied to a laser diode; generating, by the control circuit, an analog drive signal corresponding to the digital description of the current pulse; communicating, by the control circuit, the analog drive signal to the laser diode; receiving…
