Tunable metasurface beam deflector

Dielectric Antenna Arrays and other Photonic Structures

Subwavelength dielectric structures support a series of multipole resonances. We are investigating how such phenomena can be exploited in novel metamaterial, photodetector, light-emitting, and optical forces technologies.
In-plane dipole radiation pattern

Molecular Antennas

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.

2D Hybrid Organic/Inorganic Perovskites

Layered hybrid organic/inorganic perovskites, e.g., Ruddlesden−Popper phases, offer synthetic means to define self-assembling multiple quantum-well structures with excellent optoelectronic properties. We have recently resolved and described the quantum-mechanical and classical origins of absorption and emission anisotropies, and have discovered unconventional magnetic dipole radiation processes in layered HOIPs.
