Researchers design new self-powered ultraviolet photodetector

Ultraviolet (UV) light detection can revolutionize industries such as civil engineering, military defense, aerospace exploration, and medical research. The future of electronics relies heavily on energy-efficient devices ...

Photoacoustic remote sensing microscopy for lipid imaging

Photoacoustic imaging is a cutting-edge technology that uses light and sound to create images of the inside of the body. When a pulsed laser illuminates the surface of biological tissue, part of the photon energy is absorbed ...

A new way to share secret information, using quantum mechanics

Quantum information is a powerful technology for increasing the amount of information that can be processed and communicated securely. Using quantum entanglement to securely distribute a secret quantum state among multiple ...

Optically controlled metasurfaces for dynamic dual-mode modulation

Dynamic control of terahertz (THz) waves at will with an ultra-compact device is important for THz technologies in biomedical imaging, telecommunications, detection, and beyond. However, tunable THz devices made of conventional ...

Using optics to trace the flow of microplastics in oceans

Microplastics are tiny plastic particles less than 5 mm in diameter that have emerged as a novel marine environment pollutant. Microplastics usually result from a breakdown of larger plastic debris but can also be generated ...

High-speed super-resolution microscopy via temporal compression

As an indispensable tool for observing the microcosmos, optical microscopy has boosted the development of various fields, including biology, medicine, physics, and materials. However, optical diffraction imposes a spatial ...

Distortion-free structured light

An exciting prospect in modern optics is to exploit patterns of light—how the light looks in its many degrees of freedom—often referred to as "structured light." Each distinct pattern could form an encoding alphabet for ...
