Abstract: We introduce a photoresist based on methacrylate copolymers bearing photochromic spirothiopyran moieties as side groups that can crosslink via supramolecular interaction between the chromophores. Upon two-photon excitation, the resist is capable of generating freestanding three-dimensional… read more here.

Abstract: We introduce optically clear and resilient free-form micro-optical components of pure (non-photosensitized) organic-inorganic SZ2080 material made by femtosecond 3D laser lithography (3DLL). This is advantageous for rapid printing of 3D micro-/nano-optics, including their integration directly… read more here.
