Topologically protected optical quasiparticles with sophisticated vectorial structures, i.e. analogous optical skyrmions, have attracted much attention, and they are classified into different topological textures, such as Neél-, Bloch-, and anti-skyrmion. However, the generation and application of analogous optical skyrmions are still an emerging topic in their infancy.
We herein propose a compact and robust approach to generate analogous optical skyrmions based on a single-path polarization interferometer with a spatial light modulator (SLM). Also, we report on the first demonstration of analogous optical skyrmions induced exotic surface reliefs onto azopolymers associated with the trans-cis-trans isomerization reaction.
