Abstract

Achieving ultrahigh-speed electro-optic modulators (subterahertz modulation bandwidths) is shown to be feasible in the thin-film lithium niobate integrated photonic platform. Design guidelines for optimization of the main radio-frequency and optical parameters are presented, and 3-dB modulation bandwidth up to 400 GHz is proved attainable in 3-mm-long devices. Such unprecedented bandwidths pave the path towards utilizing the devices in advanced optical communication systems.

摘要

在薄膜铌酸锂集成光子平台上实现超高速电光调制器（亚太赫兹调制带宽）被证明是可行的。本文给出了优化主要射频和光学参数的设计指南，并证明在3毫米长的器件中可实现高达400吉赫兹的3分贝调制带宽。如此前所未有的带宽为在先进光通信系统中使用这些器件铺平了道路。
