A team of photonics and electronic engineers at Kyoto University has found a way to overcome the shortcomings of photonic-crystal surface-emitting lasers (PCSELs) that have prevented their use in industrial-scale cutting ...
Vortices of light, null regions of intensity surrounded by spiral phases, make up the skeleton of a wavefield and influence the properties of light. Since the discovery of the tight connection of optical vortices and orbital ...

A time crystal, as originally proposed in 2012, is a new state of matter in which the particles are in continuous oscillatory motion. Time crystals break time-translation symmetry. Discrete time crystals do so by oscillating ...
Non-classical states of light such as single photons and entangled photons are key ingredients for chips dedicated to quantum computation, quantum sensing, quantum measurement, etc. Fabrication of a traditional chip is hard, ...
