Abstract: |
The role played by the multifunctional ferroelectric oxides in optoelectronic engineering becomes more and more important. The pyroelectric effect of ferroelectrics can be used for fabricating new generation of uncooled infrared detectors. 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. This review briefly describes the applications of lead zirconate titanate and barium strontium titanate materials in infrared detectors, waveguides, optical switches, 1D photonic crystals, and optical mirocavity.
