Overview
My research focuses on the confinement of electromagnetic energy and charged particles in the nano- to atomic-scale dimensions and the interactions between such confined systems. This involves the sub-diffractional confinement of light using 'polaritons' within the optical spectral domain (primarily the infrared), the design of nanoscale optical components, the role of polaritons in enhancing thermal conductivity, and identifying and characterizing novel optical, electro-optical, and electronic materials.
