Figure 1 Schematic diagram of a nonlinear metasurface composed of asymmetric meta-atoms based on guided mode resonance and bound states in the continuum. Nonlinear optics is a branch of optics that ...

Experimental demonstration that non-harmonic two-color femtosecond excitation produces a ~1,000× stronger supercontinuum in water compared to conventional single-color excitation. Scientists at ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

Theoreticians report that they found no evidence of any universal topological signatures after performing the first ab initio investigation of high harmonic generation from topological insulators.

A recent article in Advanced Materials reports a new fabrication method for nonlinear optical components using nanostructured polycrystalline lithium niobate (LN). The study addresses key limitations ...
