Optical vortex and vector field are two important types of structured opticalfields. Due to their wide applications and unique features in many scientificrealms, the generation, manipulation and measurement of such fields haveattracted significant interest and become very important topics. However, mostways to generate vector fields have a trade-off among flexibility, efficiency,stability, and simplicity. Meanwhile, an easy and direct way to measure thetopological charges, especially for high order optical vortex, is still achallenge. Here we design and manufacture a prism: polarization interferometricprism (PIP) as a single-element interferometer, which can conveniently convertan optical vortex to vector fields with high efficiency and be utilized toprecisely measure the topological charge (both absolute value and sign) of anarbitrary optical vortex, even with a high order. Experimentally we generate avariety of vector fields with global fidelity ranging from 0.963 to 0.993 andmeasure the topological charge of an optical vortex by counting the number ofpetals uniformly distributed over a ring on the output intensity patterns. As aversatile tool to generate, manipulate and detect the spin-orbital state ofsingle photons, PIP can also work in single-photon regime for quantuminformation processing. In experiment, the PIP is utilized as a spin-orbitControlled-Not gate on the generated 28 two-qubit states, achieving the statefidelities ranging from 0.966 to 0.995 and demonstrating the feasibility of thePIP for single photons.
