Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Researchers have demonstrated a new visible light communication system that uses a single optical path to create a multi-channel communication link over the air. This approach could be used as a ...

In discussions about generative AI, the performance and number of GPUs often take center stage. However, simply preparing a large number of GPUs is not enough to fully unleash their power. It is also ...

Newswise — As an important form of optical micromanipulation, optical particle transport utilizes phase gradient forces to drive particles along predefined trajectories. Leveraging its advantages of ...

The lithium niobate thin-film modulator was designed to achieve a modulation frequency of 350 kHz within the 0–2π phase range, further realizing high speed control of optical field coherence.

Plasmonic modulators are tiny components that convert electrical signals into optical signals in order to transport them through optical fibers. A modulator of this kind had never managed to transmit ...
