Laser developer Omicron Laserage, based in Rodgau, Germany, announced at last week's Optatec show in Frankfurt that it has created "what no other manufacturer has achieved". Omicron's new diode laser, ...

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 ...

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 ...

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 ...

Interfacing laser driver circuits with commercially available laser diodes at high data rates can be a complicated and frustrating task. This application note is intended to briefly address this topic ...

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 ...
