论文摘要
电动光学调节器是许多信号处理系统的关键，必须遵守电气和光学约束所给出的要求。区分电荷驱动（CD）和现场驱动（FD）设计，我们回答了一个问题，即是否可以基于新兴的电形材料来要求调节器的基本绩效益处。在初级指标之后，我们比较了新兴的电磁和电吸收调节剂的性能，例如石墨烯，透明的导电氧化物和基于电荷注入的SI与传统FD调节剂的性能，例如基于基于硅锂和量子的量子限制的Stark Stark效应的传统FD调节剂。我们表明，出于根本原因，FD调节剂在常规波长尺度波导中始终优于CD。但是，对于具有子波长度模式的波导，例如在等离震源的辅助模式下，新兴的CD设备确实具有很高的竞争力。
Electro optic modulators being key for many signal processing systems must adhere to requirements given by both electrical and optical constrains. Distinguishing between charge driven (CD) and field driven (FD) designs, we answer the question of whether fundamental performance benefits can be claimed of modulators based on emerging electro-optic materials. Following primary metrics, we compare the performance of emerging electro-optic and electro-absorption modulators such as graphene, transparent conductive oxides, and Si, based on charge injection with that of the legacy FD modulators, such as those based on lithium niobate and quantum confined Stark effect. We show that for rather fundamental reasons, FD modulators always outperform CD ones in the conventional wavelength scale waveguides. However, for waveguide featuring a sub-wavelength optical mode, such as those assisted by plasmonics, the emerging CD devices are indeed highly competitive.
