In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: t… ...

This report describes the development of low-power balanced diode modulators suitable for amplitude modulation by television or sound signals of a carrier in the frequency range 10-1000 Mc/s. From ...

Here we demonstrate a directly modulated photonic crystal nanocavity light-emitting diode (LED) with 10 GHz modulation speed and less than 1 fJ per bit energy of operation, which is orders of ...

LED lights are the latest thing in home lighting, using less energy and lasting longer than their incandescent cousins. How do they work? Find out in the latest installment of Appliance Science.

The two leading flat-panel display technologies—liquid crystal displays and organic light-emitting diode displays—have been compared. Liquid crystal displays (LCDs) currently have the upper ...

At the age of 15, he became fascinated by crystal diodes and published his first article about radio when he was 17. Rufus Turner was–among other things–the first black licensed radio operator ...

While they're not the fanciest or newest tech, LCD and LED TVs are still pretty common and usually inexpensive. Is one better than the other, though?

Cr4+:YAG Crystal is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd and Yb doped lasers at wavelength from 0.8 to 1.2 µm. The preliminary experiments of LaserMa’s ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to ...

This report describes the development of low-power balanced diode modulators suitable for amplitude modulation by television or sound signals of a carrier in the frequency range 10-1000 Mc/s. From ...
