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).

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 ...

[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 ...

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 ...

Silanna Semiconductor has begun full‑scale production of what it describes as the industry’s smallest and most efficient ...

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 ...
