Abstract

Magnetophotonic crystals with periodic arranged of permeability can reflect terahertz waves through Bragg diffraction. The micrometer order photonic crystals were fabricated by stereolithographic method. In this process, acrylic resin including metallic and oxide glass particles was spread on a polyethylene substrate with 10 μm in layer thickness. Then a two dimensional pattern was formed by illuminating visible laser with 405 nm in wavelength. Through stacking layer process, a micrometer order three dimensional structure was constructed. Metallic and oxide glass composite material was obtained through heat treatment. The amorphous structure of the metallic glass was kept by low temperature heating process. The transmission spectrum of terahertz wave for the fabricated crystals was measured by terahertz time domain spectroscopy.
