Photonic Devices Having Degenerate or Split Spectral Band Edges
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.
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.
