This light chaser circuit (music-operated lighting effect generator) comprises five sets of 60W bulbs that are arranged in zig-zag fashion. The bulb sets glow one after another depending on the ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress conditions. The main operating parameter is ...

Light flicker inside a building is usually associated with loose wiring, faulty switches, or poor electrical connections. But there are many situations in which lights flicker even when the ...

Just as optical fibers have replaced most electrical wires for long-distance telecommunications, light-based circuits may replace electrical ones in applications involving vast flows of data within ...

Transmitting information using light is more energy efficient than using electrical signals. Unfortunately, for small-scale applications, light-based encoding through electro-optic modulators (EOMs) ...

There's a long wish list for a workable quantum computer: a viable system must be fast, compact and stable. The first integrated optical quantum logic circuits are a step in the right direction. Quite ...
