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 oil 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 mu s and bistable characteristics which are not possible with nematic liquid crystal microlens arrays.
