Abstract
Provided are techniques for generating optical vector beams (e.g., radially and azimuthally polarized light) using passive or active phase stable optical interferometry. Techniques may split an input optical beam into at least two output beams, and then couple those beams simultaneously into a passively phase stable optical interferometer. Beam splitting may be achieved by a diffractive optical element and coupling may be achieved by a single refractive optical device (lenses) or by a single mirror device (e.g., parabolic and spherical). The interferometer may provide the ability to manipulate (or transform) the polarization of part of the wavefront of each beam, as well as the ability to manipulate (or transform) the phase of part of the wavefront of each beam, such that the beams when combined have a vector beam polarization state.
