Herein we report on a simple, low cost, and feasible route for the construction of PbZr0.4Ti0.6O3 (PZT)- or Ba0.9Sr0.1TiO3 (BST)-based optical microcavities using a single chemical solution containing polymer polyvinylpyrrolidone. The obtained multilayer systems not only exhibit good ferroelectric performance, but also display well-defined resonant modes with a quality factor of no < 66. Compared with PZT microcavities, the optical properties of the BST microcavities appear to be superior.
