Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

Researchers have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a ...

The new FFPF60B150DS co-packaged damper and modulation diode pair is designed to improve horizontal voltage control in color televisions and monitors. Housed in fully isolated TO-220 package, the two ...

Anyone who has just spent several thousand pounds on a semiconductor laser diode should think twice before simply connecting it to a conventional laboratory power supply. To avoid damaging your laser ...

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today that it will begin shipping samples of its 100Gbps (53Gbaud) four-level pulse-amplitude modulation (PAM4) ...

The data usage of the modern world is absolutely mind-boggling. We have giant, air-conditioned buildings dedicated to shuffling bits around at high speed. And for what? To ensure that Instagram can ...

Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has developed a world's first fully monolithically integrated laser diode for use in transmission devices ...

“Diode Modulation” is a simple means of creating an AM signal. The exciter creates the carrier. Audio is combined to create amplitude and sidebands and then sent to a half-wave rectifier. This signal ...
