Terahertz Wave Control for Enhanced Wireless and Biomedical Technology
Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass through many materials without causing damage, making them useful for security scanning, medical imaging, and... -
The Changing Sky That Plants See
Researchers from Kyushu University have developed a new numerical model to explain the behavior of sunlight under various weather conditions. Unlike previous methods that focused on how plants perceive sunlight as a pure source... -
Real-Space Imaging of Surface Carrier Transport in 2D Perovskites
Efficient carrier transport is essential for high-performance light-conversion devices, yet two-dimensional (2D) perovskites face significant challenges due to their quantum well (QW) structures. The inorganic perovskite layers,...

Ultrafast Laser Method Assists in Directing Light
Photonic technologies and applications often require light signals to be manipulated in three dimensions such as in optical computing, fiber imaging, data transport and quantum technologies. To be useful, the shape and direction of light must be... -
Sub-50 Femtosecond Pulse Lasers for Gentler Multiphoton Microscopy
Finding the ideal ultra-fast laser source for a multiphoton imaging setup is not trivial. It is a fine balance between peak power, pulse energy and laser wavelength. In this white paper we discuss important laser parameters and the impact these... -
Optics Measure How Microplastics Hinder Light Flow in Our Oceans
Plastics have only been around since the 1950s and yet they’re everywhere: scattered in our lakes, rivers, floating on the top of oceans, and dropping to the bottom. Back in the 1950s and 60s, plastics were hailed as a useful invention, used... -
Terahertz Microscopy Explores New Material for Solar Cells
A team of scientists from the Department of Energy’s Ames National Laboratory gained insight into a possible alternative material for solar cells. The team, led by Jigang Wang, senior scientist from Ames Lab, developed a microscope that uses... -
Gaps noted in lung cancer diagnostics and treatment
Lung cancer is most common cancer in men and the 2nd most common cancer in women according to World Cancer Research Fund International. Lung cancer is the leading cause of cancer death overall and among both men and women, according to the American... -
Advances in Optical Coherence Tomography
Optical coherence tomography (OCT) uses light for cross sectional imaging and is most commonly used for medical diagnostics, but it also has uses in applications such as analyzing paint on automobiles, nondestructive testing, and more. The global... -
Brain Research Advances with Light-Based Technologies
Common methods of brain imaging present many challenges: some are invasive, others may contain harmful radiation, and many are difficult to use or require the patient to remain absolutely still throughout the process. Today researchers are...
