Integrated hybrid magneto-optics (Inthymo)

这个为期三年的战略项目涉及一系列基于磁光薄膜技术的新型集成器件的开发。拟议的理论和实验研究将允许来自INRS-EMT的大学团队成员与他们的工业伙伴合作，领导加拿大和国际努力寻找低成本，高性能，集成的全光隔离器。我们的兴趣源于磁光学对隔离器/环行器形式的通信和传感应用发展的影响，隔离器/环行器保护光源免受反射引起的不稳定性。使用中的大量隔离器代表了光电子行业的一项重大投资。然而，进一步的实际进展取决于集成，很明显，磁光元件（如隔离器/模式转换器）与二极管激光器的单片集成是现在必须解决的任务。该项目的目标有三个方面：(A)完成单模、非互易波导和光隔离器的理论分析；(B)开发基于YIG衬底的高质量磁光薄膜（薄膜将使用激光烧蚀技术沉积），用作我们设备的上层包覆层；(C)提供包含磁光层的波导制造和表征的初步概念验证实验。由此产生的高度紧凑的设备可能会对几个学科产生巨大影响，如电信工程、光谱学和计量学。我们设计的简单性和成熟的半导体波导技术很可能导致成本/性能和大规模可复制特性，这是成功商业化的先决条件。最后，从这个项目中产生的新知识以及与这项工作的不同阶段有关的高素质人员的培训肯定会有助于提高加拿大的全球竞争力，特别是在最先进的高技术部门。

This three year strategic project is concerned with the development of a series of novel integrated devices basec on a magneto-optic thin film technology. The proposed theoretical and experimental research will allow the university team members from INRS-EMT, in collaboration with their industrial partners, to lead Canadian and international efforts in searching for low-cost, high performance, integrated all-optical isolators. Our interest stems from the impact of magneto-optics on the development of communications and sensing applications in the form of isolators/circulators, which protect light sources from the instability caused by reflections. The sheer number of bulk isolators in use represents a major investment by the photonics industry. Nevertheless, further real progress depends upon integration and it is clear that the monolithic integration of magneto-optic components such as isolators/mode-converters with diode lasers is the task that must now be addressed. The objectives of this project are three-fold: (A) To complete a theoretical analysis of single mode, non reciprocal waveguides and optical isolators; (B) To develop high quality magneto-optic thin films based on a YIG substrate (the films will be deposited using a laser ablation technique) to be used as upper claddings in our devices and (C) To provide preliminary proof-of-concept experiments of the fabrication and characterization of waveguides incorporating magneto-optic layers.The resulting, highly compact devices could have a dramatic impact in several disciplines, such as telecommunication engineering, spectroscopy and metrology. The simplicity of our design and the mature technology of semiconductor waveguides may well lead to the cost/performance and mass-reproducible characteristics which are prerequisite to successful commercialization. Finally, the new knowledge generated from this project and the training of highly qualified personnel associated to the different stages of this work will certainly contribute to enhance Canada's global competitiveness, especially in the most advanced high-technology sectors.
