Imagine arriving at a busy location with people moving around and a multitude of visual and other sensory cues vying for your ...

A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a ...

Abstract: In the environment where traditional radio frequency (RF) communication systems face significant challenges, such as mining operations or nuclear testing laboratories, reliable alternative ...

When a predator like a lion walks through the grasslands, it makes its presence known by roaring, which can be heard miles away. Since the lion is at the top of the food chain, it doesn’t particularly ...

Ultraviolet or infrared light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. UV (100–400 nm) and NIR (0.75–1.4 μm) ...

Researchers from the Advanced Science Research Center at CUNY Graduate Center (CUNY ASRC) have made a breakthrough in the design of nonlinear metasurfaces. Described in eLight, the team's device is a ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science ...

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a single photon can carry. This leap could make quantum communication more ...

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that enables stable data transmission even under strong ambient light. By ...

A VLC system consisting of a transmitter and a receiver was constructed, and a serializer/deserializer using 8B13B coding was implemented on an FPGA. The data modulated onto the LED light were ...
