摘　　要：光学超晶格是一种基于准相位匹配技术的非线性光学材料。通过铁电畴工程研制出不同微结构的光学超晶格,可以实现高效灵活的非线性频率转换,并对光场进行多维调控。光学超晶格的基质材料,经历了从体块到薄膜的发展,伴随着两种材料体系超晶格制备技术的突破,催生了激光变频技术、非线性光场调控和多功能集成光量子芯片等重要应用。Optical superlattice is a nonlinear optical material based on the quasi phase matching technology.Optical superlattice with different microstructures enabled by ferroelectric domain engineering can efficiently and flexibly realize nonlinear frequency conversions as well as multi-dimensional manipulation of the light field.The host material of optical superlattice has been undergoing the development from bulk to thin film.With the breakthrough of the fabrication techniques of the two material platforms,diverse important applications have been spawned,such as laser frequency conversion technology,nonlinear light field manipulation and multi-functional integrated photonic chips.
