Claim:
1. A method for fabricating a nanoantenna array, comprising: forming a resist layer on a substrate; forming a focusing layer having a dielectric microstructure array on the resist layer; diffusing light in a specific direction by using a linear diffuser; forming an anisotropic pattern on the resist layer by illuminating the light diffused by the linear diffuser on the focusing layer and the resist layer; depositing a material suitable for a plasmonic resonance onto the substrate and the resist layer on which the pattern is formed; forming a nanoantenna array on the substrate by removing the resist layer and the material deposited on the resist layer; and determining a size of the dielectric microstructure based on an aspect ratio of the pattern to be formed.
