Photonic Integrated Circuits Using Electrochromism

本项目研究已建立的光子集成电路与显示光离子功能的材料的组合，该功能通常被称为电致变色。我们提出通过改变混合离子电子导体的电荷状态，在片上波导中的光相移驱动。合适的导体包层应被引入到已建立的微细加工线，使新一代的芯片集成，固态微调和开关器件的不同波长的制度。该项目的目标是通过应用混合离子电子导体的定制活性包层，在氮化硅和硅波导中进行受控光调制的实验演示。我们的目标是实现一个紧凑的（10 μm）微调设备，具有短的延迟，工作在低电能（< 1 nJ），并通过低控制电压（< 5 V）激活。该项目将作为一个在硅光子学方面具有专业知识的工程团队和一个专门研究薄膜电池材料的材料研究团队的共同努力来执行。

This project investigates the combination of established photonic integrated circuits with materials showing an opto-ionic function which is commonly termed as electrochromism. We propose actuation by optical phase shift in on-chip waveguides by changing the charge-state of the mixed ionic-electronic conductors. Suitable conductor-claddings should be introduced into the established lines of microfabrication, enabling a novel generation of chip integrated, solid-state trimming and switching devices for different wavelength regimes. The goal of the project is the experimental demonstration of the controlled light-modulation in silicon-nitride and silicon waveguides by applying tailored active claddings of mixed ionic-electronic conductors. We target to achieve a compact (10 μm) trimming device with short latency that works with low electrical energy (< 1 nJ) and is activated by low control voltages (< 5 V). The project will be performed as a joint effort of an engineering team expertized in silicon photonics and a materials research team specialized in thin-film battery materials.
