The field of topological photonics, specialized in the development of a class of materials known as photonic topological insulators, has advanced considerably over the past few decades. Photonic topological insulators have ...
Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...
(Phys.org)—Physicists have demonstrated a new mode of electromagnetic wave called a "line wave," which travels along an infinitely thin line along the interface between two adjacent surfaces with different electromagnetic ...
(Phys.org)—Physicists have proposed a way to braid three beams of light by guiding the beams along swirling, vortex-shaped defects in the optical medium through which the beams travel. The braided light would have an unusual ...
(Phys.org)—One promising approach for scalable quantum computing is to use an all-optical architecture, in which the qubits are represented by photons and manipulated by mirrors and beam splitters. So far, researchers have ...
(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the efficiency with ...
Directing light from place to the place is the backbone of our modern world. Beneath the oceans and across continents, fiber optic cables carry light that encodes everything from YouTube videos to banking transmissions—all ...
