Abstract

We fabricated a fast bistable ferroelectric liquid crystal (FLC) microlens array by combining a focusing unit with a tuning unit. The focusing unit with birefringent liquid crystalline polymer focuses the incident light depending on the polarization. The tuning unit with ferroelectric liquid crystal controls the polarization state of the incident light. The resultant microlens array shows fast switching time of the order of 10 μs and bistable characteristics which are not possible with nematic liquid crystal microlens arrays.
