Fabrication of a High Quality Etching Mask for Two-Dimensional Photonic Crystal Structures

Abstract
The influence of different fabrication parameters on polymethyl methacrylate (PMMA) etching mask for two-dimensional photonic crystal structures are studied.The results show that high quality PMMA etching mask can be realized by optimizing parameters such as PMMA thickness,electron beam exposure dose,developing time,and fixation time.-
