摘要：
A process for fabricating alumina micro photonic fractals with a Menger sponge structure using micro-stereolithography was investigated. After removing resin of the preformed sponges with alumina/resin composite at 600 degrees C in air for 2 h, they were sintered at 1500 degrees C for 2 h. An array of dense alumina micro photonic fractals with stage 3 Menger sponge structure of a 8 10 to cube size showed a sharp localization of terahertz wave at 0.27 THz. Similarly, stage I and 2 samples localized terahertz waves at 0.21 and 0.24 THz, respectively. These localization frequencies were in good agreements with the TLM simulations.
