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

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 ...

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, ...

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 ...

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.

Although red diodes did exist to pump the crystal, diode manufacturers concentrating on the important telecoms wavelengths had not developed red diodes in favour of their near-infrared cousins.

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 ...

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.

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.
