Abstract
Active photonic crystal devices for controlling an optical signal is disclosed. The devices include a planar photonic crystal with a defect waveguide. In one embodiment of the invention, the propagation of the optical signal is controlled by changing a dimension of the planar photonic crystal structure. In another embodiment, the propagation of the optical signal is controlled by inserting rods into the columnar holes of the planar photonic crystal structure. In a third embodiment of the invention, the propagation of the optical signal is controlled by filling the holes of the planar photonic crystal structure with fluid.
