About Us

Our research concerns novel physical phenomena, both quantum-mechanical and classical in nature, that occur when light interacts with objects of subwavelength dimensions. These objects may be self-assembling molecular crystals, or strategically engineered dielectric structures. We are particularly interested in antenna-like effects arising from oriented dipolar and multipolar resonances, which can be exploited, e.g., to engineer the directionality of absorbed or emitted light. Alternatively, we study naturally occurring radiation/absorption patterns to understand the structure and quantum-mechanical properties of the emitting material. Ultimately, this research may lead to a future where optical properties are controlled and engineered at the atomic or molecular level.
