The Influence of Resin Molds Fabricated with Different Forming Angle by Stereolithography on the Transmission Performance of Photonic Crystals

Abstract:

In order to study the influence of fabrication accuracy on the transmission performance of photonic cystals, the resin molds with inverse diamond structure with the same size were fabricated in different forming angle (30°,60°,90°) by stereolithography (SL). The alumina PCs with diamond structure were obtained combining the molds and gel-casting. The results showed that different forming angle of three kinds molds resulted in the change of the size and relative angle of their cells, and the PCs fabricated were also. The transmission properties of PCs had an obvious change in the width and smoothness of the band gap, which displayed that the resin molds by SL resulted in fabrication errors would affect the transmission properties of PCs. In the practical fabrication of diamond-structure PCs, fabrication errors caused in the different forming angle needed to be considered when SL technology was utilized to fabricate the molds, which also fit complex molds.
