Abstract

Abstract Photonic waveguides are the most fundamental element for photonic integrated circuits (PICs). Waveguide properties, such as propagation loss, modal areas, nonlinear coefficients, etc., directly determine the functionalities and performance of PICs. Recently, the emerging waveguides with bound states in the continuum (BICs) have opened new opportunities for PICs because of their special properties in resonance and radiation. Here, we review the recent progress of PICs composed of waveguides with BICs. First, fundamentals including background physics and design rules of a BIC-based waveguide will be introduced. Next, two types of BIC-based waveguide structures, including shallowly etched dielectric and hybrid waveguides, will be presented. Lastly, the challenges and opportunities of PICs with BICs will be discussed.
连续介质中束缚态光子波导的基本原理及应用
摘要光子波导是光子集成电路中最基本的元件。波导特性,如传输损耗、模态面积、非线性系数等,直接决定了pic的功能和性能。近年来,连续介质中束缚态波导(bic)的出现,由于其特殊的共振和辐射特性,为PICs的发展开辟了新的机遇。本文综述了近年来由波导与bic组成的PICs的研究进展。首先,将介绍基于bic的波导的基本原理,包括背景物理和设计规则。接下来,将介绍两种基于bic的波导结构,包括浅蚀刻介质波导和混合波导。最后,我们将讨论pic与bic的挑战和机遇。
