In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.210040, Researchers led by Professor Daewook Kim from The University of Arizona, Tucson, AZ, USA consider advances in optical ...

When the existing optical components have been discontinued or the existing optical products cannot meet the customer's application requirements, reverse optical engineering is a reliable and ...

Severe fine dust pollution over Seoul and Mexico City, being composed of the same type of fine particulate matter (PM2.5), exhibits markedly different characteristics. Seoul's air tends to reflect ...

Opaque to transparent: A strong laser illuminating a material in a low-temperature chamber. The laser changes the material's degree of transparency in a reversible way, without heating it. (Courtesy: ...

The role of light in our lives is both pervasive and primordial. Ultraviolet light probably had a role in the very origins of life, and light-driven photosynthesis underlies all but the most primitive ...

This lab course introduces students to modern topics of engineering optics. Teams of students will carry out four different projects: holography, lasers, free-space optical communication, and ...

Optical instruments are how we see the world, from corrective eyewear to medical endoscopes to cell phone cameras to orbiting telescopes. The first order optical system design covered in the previous ...

While 20th-century technology was defined by the growth of electronics, the 21st century belongs to photonics. LEDs will light households powered by photovoltaic panels and filled with displays and ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...
