We have demonstrated an approach of relatively rapid fabrication of two-dimensional (2-D) photonic crystals (PCs) with embedded defects by combining a custom-built blue-laser-writer and the technique of optical holography. The blue-laser-writer is used to define various defect patterns first, and then the optical holography is used to create 2-D PCs on the samples with the predefined defects. A beam splitter was fabricated based on this new method and characterized.
