ORLANDO, Fla., Feb. 20, 2020 — University of Central Florida (UCF) researchers have taken a step toward developing neuromorphic computers — computers that mimic neurobiological architectures present in the human nervous system — by demonstrating how to create a nanoscale device that can mimic the neural pathways of brain cells used for human vision. “Our group created a single device that mimics the eye and the brain function together,” professor Tania Roy said. “Our device can observe the image and recognize it on the spot.” The researchers grew perovskite quantum dots (PQDs)...Read full articleRelated content from Photonics MediaARTICLES2D Microlaser Arrays Enhance Stability, PowerResearchers from the University of Pennsylvania and Duke University designed and built 2D arrays of closely packed microlasers that demonstrated the stability of a single microlaser, and that...Photonics Spectra July 2021 IssueDisplay Resolution Increases by 3D-Printing Quantum Dot NanopixelsA display technology developed at the Korea Electrotechnology Research Institute (KERI) produces 3D pixels with nanoscale dimensions by 3D-printing quantum dots (QDs) embedded in polymer nanowires....Photonics.com 8/19/2020Strain Engineering of 2D Materials Enables More Effortless PhotodetectionUsing a 2D material and an approach it calls “strainoptronics,” a George Washington University research team created a photodetector that can operate with high efficiency at the...Photonics Spectra October 2020 IssueOn-Chip Deep Neural Network Detects and Classifies Images in an InstantAn optical deep neural network integrated on a chip could be a significant advancement for image classification technology.

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 HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery, and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors), and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookImage Intensification: The Technology of Night Vision: Through succeeding generations, image intensifying devices have brought vision to the dark of night.Image intensification, the basis of night vision, is a complex conversion of energy particles that occurs within a vacuum tube.
