Abstract
An optical device may include a fiber to provide a beam. The optical device may include a graded-index element to expand or magnify the beam. An input facet of the graded-index element may be adhered to an output facet of the fiber. The optical device may include an optical transformation element to transform the beam after the beam is expanded or magnified by the graded-index element. An input facet of the optical transformation element may be adhered to an output facet of the graded-index element. The optical transformation element may comprise at least one active optical element or may be non-birefringent such that orthogonal polarizations of the beam do not experience distinct phase transformations.
