Vorlesungsskript Physikalische Elektronik und Messtechnik. Photonic Crystal Research. About half of our group is dedicated to working on problems related to a new kind of material, photonic crystals (also known as photonic band-gap materials). Photonic crystals are periodic dielectric structures that have a band gap that forbids propagation of a certain frequency range of light. This property enables one to control light with amazing facility and produce effects that are impossible with conventional optics. Photonic crystals are described exactly by Maxwell's Equations, which we can (and do) solve by the application of massive computational power. Much of our research, however, is directed at achieving a higher level of understanding of these systems, so that we can predict and explain their behavior without resorting to brute force calculation. We are also interested in finding new phenomena and devices that are made possible by photonic crystals, and have already filed several patents for our discoveries.
