A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

Through their interaction, they form a new, crystalline structure ... two other optical clocks and one microwave clock from PTB were included: an ytterbium single ion clock, a strontium lattice clock ...

and instead depend more on the super-moiré structure itself and how it affects the electronic bands in the material, allowing for enhanced optical conductivity," Wilson said. Lewandowski added ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or 'optical feedback'. Once the light has achieved desirable optical gain, laser diodes release it as ...
