Abstract


Arrays of two-dimensional complexed photonic crystals (2D-cPCs) have been fabricated by a multiple-exposure nanosphere-lithography (MENSL) method utilizing a self-assembed nanosphere as a lens mask and an expanded He-Cd laser. The nanospheres were self-assembled on a photo-resist(PR). The nanospheres were self-assembled on a PR. Then, the masked PR was multi-exposed with a changing rotation angle(q) and tilt angle (g). The scanning electron microscopy reveals that MENSL is a useful tool for fabricating cPCs with various lattice structures.
