Abstract

Second-order (χ(2)) optical nonlinearity is one of the most common mechanisms for modulating and generating coherent light in photonic devices. Due to strong photon confinement and long photon lifetime, integrated microresonators have emerged as an ideal platform for investigation of nonlinear optical effects. However, existing silicon-based materials lack a χ(2) response due to their centrosymmetric structures. A variety of novel material platforms possessing χ(2) nonlinearity have been developed over the past two decades. This review comprehensively summarizes the progress of second-order nonlinear optical effects in integrated microresonators. First, the basic principles of χ(2) nonlinear effects are introduced. Afterward, we highlight the commonly used χ(2) nonlinear optical materials, including their material properties and respective functional devices. We also discuss the prospects and challenges of utilizing χ(2) nonlinearity in the field of integrated microcavity photonics.

集成微谐振器中的χ(2) 非线性光子学。
二阶(χ(2))光学非线性是在光子设备中调制和产生相干光的最常见机制之一。由于具有强光子约束和长光子寿命,集成微谐振器已成为研究非线性光学效应的理想平台。然而,现有的硅基材料由于其中心对称结构而缺乏χ(2)响应。在过去的二十年里,各种具有 χ(2) 非线性的新型材料平台相继问世。本综述全面总结了集成微谐振器中二阶非线性光学效应的研究进展。首先,介绍了 χ(2) 非线性效应的基本原理。随后,我们重点介绍了常用的 χ(2) 非线性光学材料,包括其材料特性和相应的功能器件。我们还讨论了在集成微腔光子学领域利用 χ(2) 非线性的前景和挑战。
