The developed all-optical signal processing chips pave the way for ultra-low loss, high-speed, high-efficient, high-density ...

Color-changing light-emitting fibers woven into fabric enable flexible, pixel-level displays for smart textiles, opening new possibilities for wearable communication.

Migrating to the unlicensed visible light spectrum, which spans 400 THz to 800 THz, accesses a vast bandwidth, enabling VLC ...

Scientists have spent decades searching for a way to uncover the details of these ancient, enigmatic stars. Today, a new ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night ...

Scientists at ETH Zurich have created an ultrafast modulator that surpasses the terahertz threshold, setting a new speed record for data transmission. The modulator (in gold) transfers the information ...

The width of the bright band and the dimmed band is the duty cycle of the PWM. The light modulation is normally not visible but can be detected subconsciously. Let’s take a closer look at the three ...

This article investigates the characteristics of the signal-dependent noise (SDN) and corresponding modulation design in nonlinear visible light communication (VLC) systems. We first provide the noise ...

ABSTRACT: This paper conducts a research on modulation characteristics of blue light-emitting diodes (LEDs) used in a visible-light communication (VLC) system. Through analysis of the modulation ...
