摘 要：During this project the Boston University team developed novel approaches to enhance light-matter coupling in optical devices by engineering photonic-plasmonic resonances in aperiodically ordered nanostructures. In particular, they designed, fabricated and characterized a large number of active photonic nanomaterials and structures and demonstrated unique optical properties such as broadband enhanced local field intensity, scattering, radiative (i.e., light emission) and nonlinear responses (i.e., second harmonic generation, nonlinear refractive index) using Si compatible materials and processing. Fabricated metal-dielectric devices have been integrated with planar Si chips for applications of aperiodic order to light emission, optical sensing, on-chip nonlinear generation, solar energy conversion, and singular optics. The fabrication and experimental characterization of materials and device demonstrators have been partnered with the development of efficient computational design tools based on semi-analytical multiple scattering theory, which allowed the rigorous study and optimization of large-scale aperiodic media for the first time.
