For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the ...

Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic arrays instead of engineered metamaterials. This breakthrough has enormous ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...
