Abstract：
The ever-increasing demand for high-speed data transmission in telecommunications and data centers has driven the development of advanced on-chip integrated electro-optic modulators. Silicon modulators, constrained by the relatively weak carrier dispersion effect, face challenges in meeting the stringent requirements of next-generation photonic integrated circuits. Consequently, there has been a growing interest in Pockels effect-based electro-optic modulators, leveraging ferroelectric materials like LiNbO3, BaTiO3, PZT, and LaTiO3. Attributed to the large first-order electro-optic coefficient, researchers have delved into developing modulators with expansive bandwidth, low power consumption, compact size, and linear response. This paper reviews the working principles, fabrication techniques, integration schemes, and recent highlights in Pockels effect-based modulators.
摘要：
电信和数据中心中对高速数据传输的不断增长的需求推动了先进的片上集成电光调制器的发展。硅调制器,受相对较弱的载流子色散效应的约束，在满足下一代光子集成电路的严格要求方面面临挑战。因此,人们对基于普克尔斯效应的电光调制器越来越感兴趣，利用铁电材料，如LiNbO3，BaTiO3，PZT，LaTiO3归因于较大的一阶电光系数，研究人员已经深入研究了开发具有广阔带宽的调制器，低功耗，紧凑的尺寸，和线性响应。本文回顾了其工作原理,制造技术，集成方案，以及基于Pockels效果的调制器的最新亮点。
