Abstract

While current nanofabrication techniques for manipulating light at the nanoscale focus on specific geometrical patterns using nanopatterning, nanomanufacturing, and lithography, exploring phase-changing media for these purposes remains limited. Our study presents a nanostructuring platform that utilizes nonlinear light-matter interactions to achieve controllable alterations in material geometry and phase. The base material for the platform is an oxide-polymer heterostructure. Laser-induced passivation and reshaping of 2D monolayers of such structures enable gradual phase transitions with resonant optical behavior. This platform shows promise in low-power inkless laser color printing, achieving high-resolution printing with a broad color gamut.
