Abstract: A novel, simple, and universal all-optical NAND gate using single-mode Fabry-Pérot laser diode (SMFP-LD) is demonstrated. The basic operating principle of the proposed NAND gate is the ...

There isn’t even email. “You use it when you need to, and when you put it back it disappears in your life,” said Kaiwei Tang, the chief executive of Light, the start-up that has developed ...

It's similar to the light switch on your wall but much smaller, much faster, and electrically controlled. Modern processors use two main ... we can create a NAND ("not AND") gate, which turns ...

Researchers find a faster way to etch deep holes for 3D NAND Plasma-based cryo-etching ... The team’s approach uses a cryogenic etching process using hydrogen fluoride plasma rather than the ...

If all you want to do is design something to turn on the light when ... two NOR gates on a card. Then, you needed to convert all your logic to use NOR gates (or NAND gates, if that’s what ...

Their novel approach uses light to control the electronic properties of the devices and opens the door to broader use of metal-metal contacts that could facilitate electron transport across the ...

However, some magnetic materials have an optical diode effect -- an unconventional nonreciprocal absorption of light manifested by the material itself. This effect leads to a change in ...

The new rule is not as dramatic as it might sound — 45 lumens per watt is actually well below the efficiency of light-emitting diodes ... percent of US homes use mostly or only LED illumination ...

Logic NAND Gates are available using digital circuits to produce the desired logical function and is given a symbol whose shape is that of a standard AND gate with a circle, sometimes called an ...
