Achieving dynamic, real\u2010time control over these topological features remains challenging. Here, we theoretically propose and numerically demonstrate an actively tunable platform on a silicon carbide membrane that creates lattices of diverse topological textures, including skyrmions, merons, and skyrmion bags. By exploiting the sublinear SPhP dispersion, we dynamically adjust the excitation wavelength to tune the topological character of these lattices. This enables tunability between bubble\u2010type and N\u00e9el\u2010type configurations, controlling field confinement and topology for topological textures in the electric field and the spin angular momentum. Furthermore, we identify a novel singularity\u2010type meron arising from the interplay of electric and magnetic spin components. This texture exhibits topological charge conservation in moir\u00e9 superlattices and a spatially confined spin reversal with tunable lateral sizes as low as  and skyrmion number density confinements as low as . These findings provide a versatile framework for on\u2010chip, reconfigurable topological photonic devices with potential applications in high\u2010resolution imaging and precision metrology in the mid\u2010infrared. The results can be readily extended to other topological systems, where similar dispersion relations hold.<\/jats:p>","DOI":"10.1002\/nap2.70015","type":"journal-article","created":{"date-parts":[[2026,3,24]],"date-time":"2026-03-24T09:45:25Z","timestamp":1774345525000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Tunable
