Beam shaping diffractive waveplates
Posted on 2017-11-21 - 15:18
We present and discuss opportunities opened up by a new generation of beam shaping optical elements that
combine capabilities of digital spatial light polarization converters and diffractive properties of thin liquid
crystalline films with patterned orientation of anisotropy axis (diffractive waveplates, DWs). Several functions of
the new generation beam shapers are demonstrated, among them converting a laser beam of a Gaussian profile
into a ring profile in the far field, a flattop profile, and into complex images. We also describe electrically controlled
beam shaping optical elements which can be turned Off and On within milliseconds by applying a low external
voltage. Optical, morphological and electro-optical properties of the components are characterized.
