Abstract

A novel fabrication method for apodized diffractive structures is proposed and examined experimentally and theoretically. It combines the principles of Laser Interference Lithography and a moiré effect in order to create high-quality subwavelength gratings with 2D adiabatic variation of depth. Synthesized structures can be used in optical security systems, plasmonic research and high-effective light couplers.
