Laser diodes, the devices that illuminate telecom fiber-optic cables, require light-current-voltage (L-I-V) measurements during production. These measurements let you characterize a laser diode's ...

The Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is the ...

Four New Jersey cities have begun testing new street lamps powered by light-emitting diodes. The new LED lamps are expected to reduce energy consumption significantly, have a longer life expectancy ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

The Keithley System 25, a fully customizable test system for the light-current-voltage (LIV) characterization of laser diodes and assembled laser-diode modules (LDMs), lets users choose only the ...

If you’ve played around with laser diodes that you’ve scavenged from old equipment, you know that it can be a hit-or-miss proposition. (And if you haven’t, what are you waiting for?) Besides the real ...

A working group of the international PV Quality Assurance Task Force has been undertaking research and testing initiatives aimed at improving the design and long-term reliability of module junction ...

LIVERMORE, Calif., Dec. 17, 2019 (GLOBE NEWSWIRE) -- To provide a proven test solution for probing millimeter wave (mmW) and terahertz (THz) semiconductor devices above 500 GHz, FormFactor, Inc.

A team of laser scientists in Germany say that their optical frequency reference setup has successfully completed a test run on a sounding rocket. Potentially, the achievement paves the way to a ...

With the ongoing increase in module operating current, a reliable junction box is critical for modules which are to last for 25 to 30 years. This article will analyse which factors need to be ...
