Abstract
Optical lenses, systems, devices and methods for fabricating and manufacturing diffractive waveplate lenses that allow setting the focal length sign of an optical system by positioning the lens with its front or back surface with respect to an incoming circular polarized light beam. Applications for the lenses include optical systems comprising fibers, diode lasers, waveplates, polarizers, and variable lenses, particularly, in the form of a set of polymer films with re-attachable adhesive layers. And providing a flat mirror with concave or convex function due to diffractive waveplate lens coating.
