For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT) and ...

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 ...
