The circuit shown in the figure measures relative humidity in air at the low temperatures found in applications like cold storage of food items and greenhouses. Instead of using electrical signal ...

As energy efficiency becomes a paramount issue in this day and age, reversible computing may serve as a critical step towards energy conservation in information technology. The inputs of reversible ...

The field of all‐optical logic circuits has garnered significant attention in recent years, particularly with the integration of micro‐ring resonators to process information entirely via light. These ...

Researchers have shown that single photons can be emitted in a uniform way from quantum dots arranged in a precise pattern. The team has used such methods to create single-quantum dots, with their ...

Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit ...

Founded in 1971 and operating in more than 20 countries, Coherent brings the industry’s broadest, deepest technology stack; unmatched supply chain resilience; and global scale to help its customers ...

I am always on the lookout for ideas for simple test and measurement instruments that can be used on my workbench. Over the years, I have built dozens of little test instruments and home lab ...

Researchers in Switzerland have made the world's smallest optical transistor ever from a single dye molecule. The device, which works by weakening or amplifying a "source" laser beam depending on the ...
