Nanowire (NW) lasers with the NW concurrently serving as optical cavity and gain medium are appealing for miniaturized photonic integration platforms, which have advantages of ultracompact footprint, low energy consumption, easy integration, and potential mass production.
In physics, as in life, it's always good to look at things from different perspectives.
Sharing real-time information requires complex networks of systems. A promising approach for speeding up data storage devices consists of switching the magnetization, or the electrons' spin, of magnetic materials with ultra-short femtosecond laser pulses.
For the first time, researchers have successfully generated strongly nonclassical light using a modular waveguide-based light source. The achievement represents a crucial step toward creating faster and more practical optical quantum computers.
Each year, about 100 million tons of rice husk waste is produced by milling rice to separate the grain from the husks. Researchers seeking a scalable method to fabricate quantum dots have created the first silicon quantum dot (QD) LED light by recycling rice husks.
Artificial intelligence algorithms are based on mathematical models called neural networks, inspired by the biological structure of the human brain, which is made up of interconnected nodes (neurons).
Semiconducting perovskites that exhibit superfluorescence at room temperature do so due to built-in thermal "shock absorbers" which protect dipoles within the material from thermal interference.
The maximum speed of signal transmission in microchips is about one petaherz (one million gigahertz), which is about 100,000 times faster than current transistors.
How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits.
In recent years, artificial intelligence has become ubiquitous, with applications such as speech interpretation, image recognition, medical diagnosis, and many more. At the same time, quantum technology has been proven capable of computational power well beyond the reach of even the world's largest supercomputer.
