Magnetophotonic crystals with periodically arranged magnetic materials can reflect the terahertz waves through Bragg diffraction. The micrometer order magnetophotonic crystals were fabricated by stereolithographic methods. In this process, the photo sensitive acrylic resin paste mixed with micrometer sized metallic glass and oxide glass particles was spread on a glass substrate in a 10 μm layer thickness by using a mechanical knife edge, and two dimensional images of UV ray were exposed with 2 μm in part accuracy. Through the layer by layer stacking, micrometer order three dimensional structures were formed. The metallic glass and oxide glass composite structures could be obtained through the dewaxing and sintering process with the lower temperature under the transition point of metallic glass. The amorphous structure formation after the heat treatment was verified by a X-ray diffraction analysis. A transmission spectrum of electromagnetic wave in terahertz frequency ranges for the formed magnetophotonic crystals with a diamond lattice structure was measured by using terahertz time domain spectroscopy.
