Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

In low power laser diode modules the designer has the option to use the classical discrete solution or take advantage of fully integrated driver ICs. Often the component cost is the only driving ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

This file type includes high resolution graphics and schematics when applicable. A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the ...
