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 ...

For advertising and promotion, light chaser circuits are used to produce lighting animation sequences to attract attention like the movie theater marquee. The device contains a lighting controller ...

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 ...

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 ...

According to the most recent data from the World Bank, 15 percent of the world’s population—approximately 1.1 billion people—lacked access to electricity in 2014. In 1994, approximately 27 percent of ...

The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers ...

The cost of 3D printing has come down dramatically to the point you can set up a small printer in your home. Those printers only spit out little plastic baubles, though. The cutting edge of 3D ...

Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, offering a simple route to ultracompact and low loss light circuits.
