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).
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 ...
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 ...
Most of us have Ethernet in our homes today. The real backbones of the Internet though, use no wires at all. Optical fibers carry pulses of light across the land, under the sea, and if you’re lucky, ...
