Tech Breakthrough with Nanoscale Optical Switch

Facebook X LinkedIn Email
Photons may someday replace electrons inside cellphones, automobiles and other products. This shift got a recent boost with the development of an ultrafast, ultrasmall optical switch. The new device, developed by a team from Vanderbilt University, the University of Alabama at Birmingham and Los Alamos National Laboratory, is now the smallest of the existing ultrafast optical switches, representing a major breakthrough in light-detecting electronic technology. Containing individual switches measuring only 200 nm in diameter, this new optical device can turn on and off trillions of...Read full article

    metamaterial
    Metamaterials are artificial materials engineered to have properties not found in naturally occurring substances. These materials are designed to manipulate electromagnetic waves in ways that are not possible with conventional materials. Metamaterials typically consist of structures or elements that are smaller than the wavelength of the waves they interact with. Key characteristics of metamaterials include: Negative refraction index: One of the most notable features of certain...

    optoelectronics
    Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
