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).

If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current duration is measured in ...

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 ...

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will begin shipping samples of its 50Gbps distributed-feedback (DFB) laser diode for optical-fiber ...

Many hobbies seem to have a subset of participants who just can’t leave well enough alone. Think about hot rodders, who squeeze every bit of power out of engines they can, or PC overclockers, who ...
