The project titled Fabrication by photolithography of Optical Elements with Large Apertures and Complex Aspherical Surfaces (LACAS) will development of technology based on microfabrication methods for realizing large aperture optical elements with complex aspherical optical surfaces for generating helical wavefront beam carrying orbital angular momentum (OAM) for high power lasers and Bessel beams of zeroth and higher order for free space optical communications. Also, in the framework of this project, free form optical components with the functionality of sorting beams with helical wavefronts as a function of their OAM and with applications in quantum information will be fabricated. The proper functionality of the fabricated components and a high quality of their optical surface will validate the technology

Objective: The development of technology based on microfabrication methods for realizing large aperture optical elements with complex aspherical optical surfaces.
