The National Science Foundation (NSF) has awarded a University of Central Florida-led team $400,049 to develop photon tunnels, new devices for concentrating and controlling light. Concentrating light is used in a range of electronics and machines such as computers and cell phones to fiber optics and sensors. These devices all use conventional lenses to concentrate light, but the lenses collect and concentrate light on a specific spot, and that spot moves as light rays strike from different angles or positions. “As a result, sensors and detectors can lose energy as the source...Read full articleRelated content from Photonics MediaARTICLESUCF’s Kyu Young Han Receives NIH GrantsKyu Young Han, assistant professor in the University of Central Florida (UCF) College of Optics and Photonics, has been awarded two grants from the National Institutes of Health (NIH).

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookLaser Measurement Systems: Best Practices: When purchasing a laser, learning how to apply, troubleshoot, and evaluate that device is very important.Given the pace at which technology advances, there always seems to be a learning curve.
