Technion researchers led by Prof. Guy Bartal have created the first on-chip nanophotonic platform that deterministically generates single-photon quantum skyrmions. Using a gold circular grating to control total angular momentum (TAM) of surface plasmons, the device transforms heralded single photons into robust, topologically protected SAM-OAM entangled states with skyrmion number ±2 — without post-selection or multi-photon entanglement. This breakthrough paves the way for sc

Researchers from Japan achieve significant breakthrough in optoelectronics that can revolutionize next-generation photodetectors

New light source could enable chip-scale gas sensing tools

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. These devices use radiation pressure—the force exerted when light reflects from a surface—to generate thrust. When driven by a powerful laser, a light sail can accelerate continuously without onboard propellant, enabling faster travel across the so

Nonreciprocal interactions between light and matter lie at the heart of many exotic physical phenomena, from magnet-free optical isolation to axion-inspired electrodynamics. One particularly intriguing example is the Tellegen effect, a nonreciprocal magnetoelectric coupling predicted more than 75 years ago but long considered weak and negligible at optical frequencies. “In natural materials, the optical Tellegen effect is extraordinarily weak, making it challenging to observe

Optical waveguide microresonators on a chip created in this effort, which are ten times thinner than human hair. @CU Boulder College of Engineering and Applied Science CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and build up its intensity. Once the intensity is high enough, researchers can perform unique light operations. “O
