Researchers have discovered a method to induce chirality in non-chiral materials using terahertz light. This groundbreaking ...

This method is also applicable to the study of the local variation of the fine structure in a crystal lattice, and the so-called selected area micro-diffraction method, when used jointly with this ...

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

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

Photonic crystal surface-emitting lasers or PCSELs are laser diodes that generate laser beams through controlled light wave interaction within a photonic crystal structure. In a recent study, ...
