Project description
Metasurface-inspired artificial optical materials for optical frequency conversion
Non-linear optical frequency conversion, the conversion of input light to light of other frequencies using optical non-linearities, enables light generation over the entire electromagnetic spectrum. It has been invaluable in many applications. However, it relies on bulk non-linear crystals, which impedes miniaturisation and integration in tomorrow’s increasingly compact and low-energy devices. Inspired by recently developed non-linear metasurfaces, a new kind of 3D nano-engineered non-linear optical material will be developed by the EU-funded 3D NOAM project. The team will also develop the required nanofabrication technology to support the material’s upscaling and commercialisation.
Objective
Optical frequency conversion in bulk nonlinear crystals is used for generation of coherent light over the entire optical regime from extreme ultra-violet up to THz waves. This remarkable ability is at the core of a plethora of important technological and scientific applications. However, bulk nonlinear crystals pose strong limitations on integration, miniaturization, and control over the nonlinear interactions, holding back the further progress of optical frequency conversion technologies.
I propose to lead a great breakthrough in the field by developing a new kind of 3D nano-engineered nonlinear optical artificial materials with superior nonlinear optical properties, and free of the limitations of bulk nonlinear crystals. These materials will be inspired by recently developed nonlinear metasurfaces. It was demonstrated that nonlinear metasurfaces exhibit unprecedented nonlinear functionalities, and effective nonlinearities exceeding by far those of bulk nonlinear crystals, promising to replace bulk crystals in future nonlinear optical technologies. However, their two-dimensional designs and nanoscale thickness strongly limit their frequency conversion efficiency, with no existing practical nanofabrication approach nor theoretical proposition to overcome this limitation. Our research aims to close this gap. We will develop a new nanofabrication methodology that will allow to stack hundreds of nonlinear metasurfaces into a 3D nonlinear material in a technologically viable way. We will study new fundamental nonlinear interactions in these novel nonlinear materials, and demonstrate experimentally their superiority over bulk nonlinear crystals in conversion efficiency and functionalities. These achievements will potentially pave the way to the next era of nonlinear optical frequency conversion technologies. They will also immediately impact applications of 3D nanostructured optical materials in general, as well as may change the way we think about 3D nanofabrication.
