In brief Researchers have developed a method by which artificial crystal lattices with a large lattice constant can be created in a semiconductor material. The large lattice constant leads to a ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

I've always been fascinated by how materials break down, especially glasses and polymers that don't have a regular crystal ...

A 3-octave spectral comb is generated in a hydrogen-filled hollow-core photonic-crystal-fiber. The spectrum consists of up to 45 high-order Stokes and anti-Stokes lines generated by coherent ...
