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 ...

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 ...

Optical waveguides are structures that guide and confine light within a small cross-sectional area. In nanophotonic circuits, waveguides are typically fabricated using high-refractive-index materials ...
