Abstract
We demonstrated a polarization-selective reflective lens with a wavelength-tunability based on a cholesteric liquid crystal (CLC). The reflective CLC lens in a plano-convex shape acts as a biconvex lens due to the Bragg reflection, and exhibits wavelength-tunability and polarization-selectivity like the conventional CLC cell.
