- Spin laser on an atomic scale: the image describes the laser resonator structure consisting of two types of nanoantenna structures. The radiation is trapped in the internal structure only (yellow). The active layer of the laser - a single atomic layer - is on the resonator. The laser beam is split into two beams by the opposite spins of the photons (light particles), which can be controlled with the help of the laser pump (credit: Scholardesigner co, LTD).

Positive spin - research at the Technion was selected as one of the breakthroughs in photonics in 2023

A smart device, based on a single atomic layer, which sorts and controls the spin of photons, may lead to the development of next-generation computers
Applying a magnetic field to a non-uniform nanostructure. The measurement of the non-uniformity in the structure on the nanometer scale is performed by the optical spin Hall effect - measuring the spin splitting of the photons scattered from the structure using a "weak measurement". The spinners (blue and red) represent the two spin directions - the degree of spin of the scattered photons. (Image credit: Ella Maru Studio)

Researchers at the Technion have developed a technology that combines nano-optics and magnetism to diagnose nanometric non-uniformities in electronic chips and photons
