Fabrication of microlens arrays (see figure) is explored using photoinduced reorientation of dye-doped liquid crystals and successive photopolymerization with a single laser beam by selecting a suitable photoinitiator. Each microlens in the microlens array exhibits polarization selectivity with respect to the incident polarized light, and the arrays can be arranged in desired patterns and with desired polarization directions.
