ABSTRACT
Materials are often used to manipulate waves. materials and surfaces have provided far-reaching possibilities in achieving “extremes” in such wave-matter interaction. Various exciting functionalities have been achieved in exploiting materials and surfaces in nanophotonics and nano-optics. We have been exploring how extreme materials can give us new platforms in photonics for exploiting waves to do certain useful functions for us. Several scenarios are being investigated in my group. As one scenario, we have been developing structure platforms that can perform analog computation such as solving integral and differential equations and inverting matrices with waves as waves interact with them. Such “material machines” can function as wave-d near-speed-of-light analog computing machines, suitable for micro- and nanoscale integration. Another scenario deals with 4-dimensional materials, in which temporal variation of material parameters is added to the tools of spatial inhomogeneities for manipulating light-matter interaction. The third category for photonics is the concept of near-zero-index structures and associated photonic doping that exhibit unique features in light-matter interaction, opening doors to exciting new wave-d and quantum optical features. In this talk, I will present some of our ongoing work on extreme material platforms for photonics, and will forecast possible future research directions in these paradigms.
