 This paper proposes dual-functional transmission dielectric meta-lenses that can generate and focus different vector beams in the telecom infrared, depending on the linear polarization state in input. These meta-lenses are based on the mathematical fundamentals for the compact generation of vector beams using dual-functional optical elements, and they are designed and fabricated using silicon. The proposed approach provides new integrated optics for applications in the fields of high-resolution microscopy, optical manipulation, and optical communications, both in the classical and single-photon regimes.
