摘要

电光调制器是现代光子通信系统中产生高速光子信号的关键部件。本文研究了采用Si缝隙波导和BaTiO3层的混合EO调制器的性能，其中BaTiO3的EO效应比广泛使用的LiNbO \(_3\)强。我们证明了适当设计槽波导，BaTiO \(_3\)层和掺杂Si连接器到金属触点可以同时实现0.16 V cm的低电压长度产品\(V_\pi L\)， 50 GHz的宽调制带宽和\(<1\) dB/cm的小传播损耗。这些值表明所提出的调制器在光子通信系统中的有效使用。

BaTiO3/Si-hybrid slot-waveguide electro-optic modulator

Electro-optic (EO) modulators are crucial components to generate high-speed photonic signals in the modern photonic communication system. Here we study the performance of a hybrid EO modulator employing a Si slot waveguide and a BaTiO₃ layer, where the EO effect of BaTiO₃ is stronger than that of widely used LiNbO\(_3\). We demonstrate that an appropriate design for the slot waveguide, the BaTiO\(_3\) layer, and doped Si connectors to metal contacts can achieve a low voltage-length product \(V_\pi L\) of 0.16 V cm, a wide modulation bandwidth of 50 GHz, and a small propagation loss of \(<1\) dB/cm simultaneously. These values indicate efficient use of the proposed modulator in the photonic communication system.
