This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

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.

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, ...

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 ...

Researchers have built a miniaturized microcomb-driven terahertz wireless communication system that's 90 times smaller than conventional chips to deliver record-breaking data-transfer speeds at ...
