Stimuli responsive polymers are showing an increasing popularity in the field of smart devices. The many advantages come from their versatility, ease of use and in particular their tunability. In particular, light-responsive poly- mers offer different opportunities in terms of remote control, allowing the possibility to take advantage of different polarisation and/or frequencies. For instance, scientific literature shows the possibility of controlling optical and mechanical properties of membranes or structured polymeric samples doped with a photo-responsive molecule, upon proper irradiation with light beams. Interesting results come from the possibility to control the refractive index of a membrane or even the shape of structured micro-pillars.
