Now, applied physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have invented a new type of interferometer that allows precise control of light’s frequency, intensity and mode in one compact package.

A research team co-led by Lawrence Berkeley National Laboratory (Berkeley Lab), Columbia University, and Universidad Autónoma de Madrid has developed a new optical computing material from photon avalanching nanoparticles.

Researchers at the University of Twente solved a long-standing problem: trapping optically-generated sound waves in a standard silicon photonic chip. This discovery, published as a Featured Article in APL Photonics, opens new possibilities for radio technology, quantum communication, and optical computing.

Scientists including an Oregon State University chemistry researcher have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again.

NTT Research, Inc., a division of NTT (TYO:9432), today announced that scientists from its Physics & Informatics (PHI) Lab have achieved quantum control of exciton wavefunctions in two-dimensional (2D) semiconductors. In an article published in Science Advances, a team lead by PHI Lab Research Scientist Thibault Chervy and ETH Zurich Professor Puneet Murthy documented their success in trapping excitons in various geometries, including quantum dots, and controlling them to achieve independent energy tunability over scalable arrays.
