Mid index integrated optical modulators

作为PHD项目的一部分，我们设想建立一个厚氮化硅(SIN)平台，用于制造O波段光收发器的多路复用器(MUX/DMUX)、分路器和组合器等无源器件。氮化硅平台将与有源设备集成，以提供微米级占地面积和低功耗的高带宽。这些器件在O波段运行，并采用标准的CMOS工艺实现，将确保MUX/DMUX具有低温度敏感度，以及高速和低功耗操作。该项目的目的是制定一个集成方案和流程，以集成O波段的有源设备和SIN MUX/DMUX，以满足数据中心未来的需求。为了实现项目目标，学生将进行波导和有源器件模拟(光学和电学)，并将为所有结构设计制造掩模和工艺流程。这些设备必须在纳米制造中心制造，并在光子学实验室进行表征。这些与cmos兼容的材料和器件的集成从未被证明过，这将是硅光子学领域的一项重大成就。学生将合作完成当前EPSRC项目参考：EP/R003076/1标题：罗克利光子学和南安普顿大学：繁荣伙伴EPSRC研究主题分类：Optoelect。器件和电路EPSRC工业部门分类：通信、制造、电子、信息技术

As part of the PhD project, we have envisioned to build a thick silicon nitride (SiN) platform for the fabrication of passive devices such as multiplexers (MUX/DMUX), splitters and combiners for optical transceivers in the O-band. The silicon nitride platform will be integrated with active devices to deliver high bandwidth with a micrometre scale footprint and low power consumption. Operating in the O-band and realised with standard CMOS processing, these devices will assure a MUX/DMUX with low temperature sensitivity, together with high speed and low power operation. The project aims are to develop an integration scheme and process flow to integrate the active devices and SiN MUX/DMUX in the O band to cover the future requirements of data centres. To achieve the project goals the student will perform waveguide and active device simulations (optical and electrical), and will design fabrication masks and process flows for all the structures. The devices will have to be fabricated in the nanofabrication centre and characterised in the photonics laboratory. The integration of these CMOS compatible materials and devices have never been demonstrated and would represent a significant achievement in the field of silicon photonics. The student will collaborate on the current EPSRC project Reference: EP/R003076/1 Title:Rockley Photonics and the University of Southampton: A Prosperity PartnershipEPSRC Research Topic Classifications: Optoelect.
