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

Researchers at the University of Illinois have pulled off a laser first: they built a new kind of eye-safe laser that works ...

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, ...

Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative ...

Abstract. 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 ...

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 -4V.

Silicon (Si) vs. germanium (Ge) semiconductor diodes– germanium is still the best crystal receivers, due to the extremely low forward voltage drop; 0.3v as opposed to 0.6v-0.7v.
