The corrections to the manuscript[1] are as follows:
- 1. The author’s name “SANG TIAN” should be corrected to “TIAN SANG”.
- 2. All of the word “axion” in the text, formulas, and figures should be corrected to “axicon”. The corrected figures are given below.
- 3. In the 7th line of the results and discussion part, the equation “l1 = l2 = l” should be corrected to “l1 = -l2 = l”.

Fig. 1. Analogy of the generation schemes between the PVB and PCVB. (a) Schematic illustration of the conventional approach for generating a PVB with a series of bulky optical elements. (b) Schematic illustration of our proposed approach for generating a PCVB based on the same optical setup.
Fig. 2. Schematic principal illustrations of generating the PCVB using a single all-dielectric metasurface. (a) Phase profile of the predesigned metasurface as a superposition of the CVB, axicon lens, and Fourier transform lens. (b) Schematic illustration for generating the PCVB based on the geometric metasurface. For a RCP beam, the metasurface partly converts it into the opposite helical state, reconstructing a PCVB in the focal plane.
