  text: <jats:p>Exciton polariton condensates are macroscopic coherent states in which
    topological excitations can be observed. In this work, we observe the excitation
    of the vortices and realize tuning the topological charge by manipulating the
    pumping configurations. Using a digital micromirror device, we constructed an
    annular pumping pattern where the inner and outer rings can be easily tuned. Both
    the number and the topological charge of the vortices can be changed by slightly
    tuning the inner ring position against the outer ring. The experimental results
    can be reproduced in theory by the Gross–Pitaevskii equation. Our work offers
    to generate and manipulate vortices in exciton polariton condensates using a straightforward
    optical method.</jats:p>
