Abstract
A three-dimensional geometric photonic crystal and a method of fabricating the photonic crystal are disclosed. The photonic crystal includes a geometric structure having a plurality of electrophoretic self-assembled particles and the plurality of particles are periodically arranged at any cross sections of the geometric structure. The method includes preparing an electrophoresis deposition suspension, installing first and second electrodes in the electrophoresis deposition suspension with the first electrode being encircled by the second electrode, and applying a voltage to the first electrode and the second electrode to form an electric field between the first and second electrodes, such that particles in the electrophoresis deposition suspension are electrophoretic self-assembled, and a periodically arranged geometric structure is formed. A photonic crystal thus may have a three-dimensional geometric structure in any shape.
