Silicon and germanium nanoantennas support a series of subwavelength multipole resonances. We are investigating how such phenomena can be exploited in novel metamaterial, photodetector, light-emitting, and optical forces technologies.

Organic material typically self-assemble into highly ordered morphologies, leading to strong optical anisotropies. We are elucidating the fundamental relationship between structural and optical properties of organic materials and identifying their impact on photovoltaic device performance.
