Electromagnetically active artificial material comprising multidimensional microplasma photonic crystals

Reconfigurable photonic crystals comprising of columnar microplasmas as the active component have been realized in the Laboratory for Optical Physics and Engineering (LOPE) at the University of Illinois. Real-time tuning of the propagation properties of the crystals in the 110-170 GHz spectral interval has been achieved in such photonic crystals by changing the refractive index of the microplasma at electronic speeds. Different structures can be achieved in such crystals by filling each column of a crystal with different materials such as metals, dielectrics, and plasma. Interesting phenomena such as plasma-induced transparency, mode splitting, and Fano-like lineshapes are observed from different crystal structures under different experimental conditions. Generally, igniting plasma microcolumns in a photonic crystal will cause blue-shifting and attenuation of the Bragg resonances, as compared to static crystals. This microplasma photonic crystal can be potentially applied for sensors, filters, and microwave resonators.
