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 ...

Scientists have developed a metasurface that boosts light emission in 2D materials, paving the way for advanced flexible and ...

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