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 ...

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 ...

Where were you in 1996? Were you at the start of your career in the electrical industry or a seasoned expert in your prime? Regardless of where that year found you in your professional life, one thing ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

A thermal diode is a two-terminal nonlinear device that rectifies energy carriers (for example, photons, phonons and electrons) in the thermal domain, the heat transfer analogue to the familiar ...
