The recent advances in flat optics have challenged the limitations of conventional optics by implementing planar elements that instead of rely on dynamic phase manipulate light waves via subwavelength-spaced phase shifters with spatially varying phas

The structural evolution from void modification to self-assembled nanogratings in fused silica is observed for moderate (NA > 0.4) focusing conditions. Void formation, appears before the geometrical focus after the initial few pulses and after subseq

Securely storing large amounts of information over relatively short timescales of 100 years, comparable to the span of the human memory, is a challenging problem. Conventional optical data storage technology used in CDs and DVDs has reached capacitie

We demonstrate direct-write laser nanostructuring of semiconductor thin-films and transparent dielectrics resulting in space-variant anisotropic materials. The continuous phase profile of nearly any optical component can be achieved solely by the mea
