ur last paper is now published in Optics Communications, entitled Dual-polarization telescope system based on lens doublets with a geometric-phase lens. PDF
Here we propose a dual-polarization telescope system based on two lens doublets, each composed of a geometric-phase (GP) lens and a conventional refractive lens. The bifocal properties of this hybrid lens doublet are obtained using the ray matrix formalism. We then demonstrate the coupling of two such doublets to construct the dual polarization telescope, which yields two images with distinct magnifications for orthogonal circular polarizations. The conditions required for these two images to lie in a common plane are obtained. Experimental validation combining a liquid-crystal GP lenses and a standard refractive lenses.
