致冷

The ferroelectrics with photoelectronic, acoustooptic, and nonlinear optical effects are good candidate for constructing optical switches, power splitters, couplers, filters, frequency doublers, and integrated photonic devices. Especially, the newly developed fabrication technology for ferroelectric-based photonic crystals renders a perspective application of ferroelectric materials in photonic band-gap engineering.
