Abstract
UV-induced self-volume growth of the hybrid sol-gel glass was investigated for fabrication of an arbitrary-surface relief structure with a user-defined gray scale mask. The gray scale mask was generated through exposure of a high-energy beam-sensitive glass under an electron beam. Saw-tooth gratings of different periods were fabricated by a simple UV exposure through the gray-scale mask. Experimental results showed that the smaller the period is, the shallower the depth obtained owing to the self-volume growth effect is.
