As advancing technology pushes to further miniaturize systems while increasing processing power, optical structures which offer dynamic tunability are becoming ever more valuable. Diffractive gratings popularly offer high efficiencies and can be readily designed to provide polarization sensitivity, making them useful as dynamic structured optics. Recently, slanted wire gratings compatible with fabrication by two-photon polymerization were investigated for their ability to be mechanically tuned. Potential applications for this grating may be in mechanical sensing and beam splitting. In this study, we investigate an additional degree of tunability not previously considered by exploiting the polarization sensitivity as well as the mechanical. It is observed that the population of the −1st, 0th, and +1st transmitted orders are sensitive to changes between x- and y-axis polarization.
