Feasibility study of on-chip Avalanche Photodetector

本研究的目的是在绝缘体上硅（SOI）平台上设计和制造波导雪崩光电二极管。建立在绝缘体上硅晶片上的硅光子器件是一种微米级、高折射率的对比光子器件，可与大规模集成（VLSI）芯片上的电子控制电路真正集成。这种器件以其低功耗、小尺寸和批量生产时的低成本，有望在光通信行业中占据主导地位。ArtIC是一家领先的光子集成电路（PIC）公司，正计划开发基于SOI平台的单片集成波长可选接收器，用于下一代波分复用（WDM）无源光网络（NG-PON2）应用。基于波导的雪崩光电探测器（APD）是该器件的关键部件之一。我们的团队拥有多年的硅光子器件设计和制造经验，将与公司合作开发该产品。通过这个项目，我们的团队将利用PI实验室，维多利亚大学和CMC微系统的设备设计和制造波导APD。在项目结束时，我们预计apd将通过数值模拟得到充分理解，并在确定制造相关挑战的情况下进行制造。通过NSERC合作研发（CRD）等长期项目的持续合作，波导APD有望得到开发、实验表征和验证，以满足ITU-G.980.2对NG-PON2市场的要求。这个项目中的活动与公司构建SOI投资组合的努力高度相关。波导APD的设计/制造过程将直接集成到他们的收发器设计产品线中。这使得该公司以及加拿大高科技产业处于PON市场的前沿，预计到2025年PON市场的价值将达到430亿美元。通过该项目培训的高素质人才（HQPs）非常适合加拿大工业的需求。

The nature of the work is to conduct a feasibility study to design and fabricate a waveguide avalanchephotodiode on a silicon-on-insulator (SOI) platform. Silicon photonic devices built on silicon-on-insulatorwafer are micron scale, high refractive index contrast photonic devices truly integrable with electronic controlcircuits on a very-large-scale integration (VLSI) chip. Such devices are promised to prevail in the opticalcommunication industry for their low power consumption, small feature size, and low cost upon massproduction. ArtIC, a leading company in photonic integrated circuits (PIC), is planning to develop amonolithically integrated wavelength selectable receiver based on SOI platform for next generationwavelength division multiplexing (WDM) passive optical network (NG-PON2) applications. Waveguide basedAvalanche Photo-Detector (APD) is one of the key components for such device. Our group, with many years ofsilicon photonics device design and fabrication experiences, will collaborate with the company to develop thisproduct. Through this project, our group will design and fabricate the waveguide APD using facilities availableat PI's lab, University of Victoria and CMC microsystems. At the end of the project, we anticipate the APDwill be fully understood through numerical modelling and fabricated with fabrication related challengesidentified. In a continued collaboration through a long term project such as NSERC collaborative research anddevelopment (CRD), the waveguide APD is expected to be developed, characterized experimentally andverified to meet the requirement specified by ITU-G.980.2 for NG-PON2 market. The activity in this project ishighly related to the endeavor of the company to building SOI portfolio. The design/fabrication process of thewaveguide APD will be directly integrated to their transceiver design product line. This positions the companyas well as Canadian high tech industry at the frontlines of PON market whose value is predicted to be $43billion by 2025. The highly qualified personnels (HQPs) through this project training well suits the demand ofCanadian industry.
