Photonic Band Gap structures (PBG structures)

Photonic Band Gap structures are periodic dielectric structures that forbid propagation of electromagnetic waves in a certain frequency range.

Such photonic "crystals" not only open up variety of possible applications (in lasers, antennas, millimeter wave devices, efficient solar cell photocatalytic processes), but also give rise to interesting new physics (cavity electrodynamics, localization, disorder, photon-number-state squeezing).

Here at Iowa State University, we are currently involved in several projects both of theoretical and experimental nature. The funding for these projects are provided by Ames Lab (USDOE) through the Office of Basic Energy Sciences. Previous funding was also received from the Center for Advanced Technology Development (USDOC).
