Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses. Nagoya ...

Noise is an annoying but unavoidable part of any engineering project. Fixing noise issues is hard enough, but even just measuring how much noise an amplifier adds to your signal is tricky without ...

Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...

(Nanowerk News) Researcher at iGaN Lab, University of Science and Technology of China, have developed a multifunctional three-terminal diode that functions both as a light emitter and a detector. This ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...
