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 ...

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 ...

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).

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and talks about ...

Hybrid device: the photonic integrated chip developed in this study. (Courtesy: G Likhachev, EPFL) A new type of ultrafast tuneable laser based on low-loss lithium niobate integrated photonics could ...

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 ...

Innovation is the name of the game as laser diode makers strive to open up new markets for their products. Bookham explains that the trend towards higher powers must be matched by higher brightness ...
