Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Published in the journal Nature Communications, the ...

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.

Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements.
