PHOTONIC DEVICES HAVING DEGENERATE OR SPLIT SPECTRAL BAND EDGESTech for Transfer PatentSale 08-10-2014 University researchers have developed a photonic device configured to display photonic band gap structure with a degenerate or a split band edge. Electromagnetic radiation incident upon these photonic devices can be converted into a frozen mode characterized by a significantly increased amplitude, as compared to that of the incident wave. The device can also be configured as a resonance cavity with a giant transmission band edge resonance. Application: This invention allows one to drastically enhance the performance of existing active electromagnetic elements, such as nonlinear and active materials, as well as creating much more efficient resonance cavities.
