We pursue the capacity to create and annihilate of skyrmion structures by directly imprinting optical skyrmions, which are topologically stable structured light, onto a variety of materials. As a demonstration, we report on the generation of optical hopfion skyrmions by using a single-pass polarization shaping configuration, and the direct imprint of the polarization textures of optical hopfion skyrmions to azopolymer thin films, which exhibit photo-induced mass transport reflecting the polarization and light intensity distribution.
