The challenges of implementing optical multiplexing in the terahertz band. A novel approach based on electro-optics, using silicon fabrication to create a four-channel multiplexer operating at 350 THz ...
The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has successfully developed a highly efficient optical modulator using the organic ...
Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...
Traditional acousto-optic (AO) devices based on bulk crystal materials have weak energy confinement abilities for both photons and phonons, leading to a low AO interaction strength. Compared with bulk ...
Two-dimensional (2D) materials are a class of materials which can be reduced to the monolayer limit by mechanically peeling the layers apart. The weak interlayer attractions, or van der Waals ...
Integrated photonics is a rapidly-evolving industry sector, with infrared spectrum applications including high-speed 5G networks, biosensors on chip, and driverless cars. Researchers are now exploring ...
Improved absorption during plasma-dispersion pushes modulators to perform better. Absorption is used to push the modulators to perform better. Research by the University of Southampton’s Silicon ...
