Creation, transformation and characterization of complex light beams and coherent modes

Laser, fiber and integrated optics naturally exploit Gaussian, Bessel, helical and other complicated light beams. There is a strong need of theoretical development, physical implementation and measurement of exotic light beams in the free space, waveguiding media, meta-materials and photonics structures. Modern technologies of precise mechanical processing, interferometry, planar lithography, laser ablation and magneto-rheological finishing had already grown a strong support for beam transformation optics. Accordingly, nearly arbitrary shaped optical elements comprising aspherical surfaces, arrays of micro and nano-optical elements, graded index distributions, Bragg reflectors and diffractive grooves are now commercially available. However design of advanced optical elements, i.e. establishing relations between intrinsic optical parameters and required performance still have to provide an adequate response to the challenging needs of beam transformation and characterization. Elegant solution is provided by computer generated holograms (CGHs) implementing mode matched spatial filter or DOE.
