Micro-LED Assembly Gets Boost from Vacuum-Assisted Transfer Printing
DAEJEON, South Korea, Jan. 2, 2024 — Compared to conventional light sources like OLEDs and LCDs, microLEDs — inorganic LED chips less than 100 μm in size — show superior reliability, stability, and optoelectronic properties. Despite these advantages, their deployment into next generation display technology is encumbered by manufacturing challenges. Mass transfer with high selectivity and controllability is essential for rearranging microLED dies from a growth substrate onto a final substrate with the desired
Atomically Smooth Gold Crystals Enable Nanophotonic Applications
LONDON, July 19, 2022 — Researchers at KAIST and collaborators have demonstrated a platform to guide compressed lightwaves in extremely thin Van der Waals crystals. The researchers believe that the method, used to guide mid-infrared light with minimal loss, will enable...
Intravital Imaging Provides Insight into Liver Disease Progression
DAEJEON, South Korea, Sept. 3, 2020 — The high-resolution, 3D-viewing capabilities provided by a new microscopy method from the Korea Advanced Institute of Science and Technology (KAIST) could lead to insights into nonalcoholic fatty liver disease (NAFLD), a condition in which too much...
Cough-Recognition Camera Distinguishes Sounds Based on Deep Learning
DAEJEON, South Korea, Sept. 2, 2020 — The Korea Advanced Institute of Science and Technology (KAIST) and SM Instruments have developed a deep learning-based cough-recognition model that recognizes cough sounds in real time, and a camera that can track and record the sound of coughing...
Multilayered Liquid Crystal Formed Through Phase Separation Exhibits Multiple Colors
SEOUL, South Korea, Aug. 19, 2020 — A technique for fabricating multilayered liquid crystals could potentially replace the color-shifting ink used for preventing forgery of bank notes, ID cards, and other items. Developed jointly by researchers at the Korea Institute of Science and...
Textile-Based Display Module Is Self-Powered, Washable
DAEJEON, South Korea, March 25, 2019 — A Korea Advanced Institute of Science and Technology (KAIST) research team has developed a textile-based wearable display module technology that is washable and does not require an external power source. The team fabricated its wearable display...
Holographic Microscopy, Machine Learning Software to ID Bacteria
DAEJEON, South Korea, June 8, 2015 — Pairing holographic microscopy with machine learning software could help hospitals and the food industry screen for bacterial infection in real time. A quantitative phase imaging unit (QPIU) developed at the Korea Advanced Institute of Science and...
ODT Enhances Optical Tweezer Capabilities, Holographic Bioimaging
DAEJEON, South Korea, May 4, 2015 — A new optical diffraction tomography (ODT) technique can measure the positions of optically trapped particles in three dimensions at high speed. The method provides a more streamlined and precise way to locate and move microscopic particles than...
Sound Camera Ready to Hit the Market
DAEJEON, South Korea, May 14, 2013 — You can hear rattling inside your car, but you can’t tell where it’s coming from or how serious it is. A new sound camera potentially could save you the trip to the mechanic by pinpointing the exact location of the noise with color contours.
OSA Elects VP, 3 Directors at Large
SAN JOSE, Calif., Oct. 20, 2011 — Members of The Optical Society (OSA) have elected Philip H. Bucksbaum as its 2012 vice president, the organization announced at Frontiers in Optics 2011 this week. Three directors at large also were chosen during the election. By accepting the...
Light at the End of the Funnel: IR Becomes EUV
GARCHING, Germany, Oct. 18, 2011 — The energy of IR light pulses has been concentrated with a nanofunnel and used to generate extreme-ultraviolet (EUV) light flashes. These femtosecond flashes are thought to contain trains of attosecond pulses. Attosecond EUV light pulses are an...
Under an Unblinking Eye
Dec 1, 2009 — Used for displays in all manner of electronic gadgets, LCD panels are a mainstay of everyday life. Dozens of manufacturers – mainly in China, Taiwan, Japan and South Korea – produce a seemingly endless stream of these liquid crystal...
Gratings and Fresnel Lenses Produced with Sol-Gel Materials
Jan 1, 2005 — Optical communication devices typically need components that are not just physically small, but also economical. Researchers at the Korea Advanced Institute of Science and Technology in Taejon have developed a novel photosensitive sol-gel process...
