Essential equipemtn for state-of-the-art characterization of elctro-optic and magneto-optic thin film based devices

虽然越来越多的数据通过光脉冲在光纤网络中传输，光学计算很快就会成为现实，但用于通信目的和全光处理的光的有效控制已成为光子工程师的一个极其重要的目标。然而，这样的努力必然需要通过不同使能材料的单片集成在低成本、超紧凑光子芯片中制造若干器件。因此，本申请的PI已经建立了一个积极的研究计划，旨在开发用于光子学和光电子学应用的新型薄膜技术。特别是，他们对以下方面的制造特别感兴趣：A）高质量、低损耗电光薄膜（基于BST、PLZT和CBN）和B）高性能磁光薄膜（基于Yig和Ce-Yig），其将被直接沉积在其他铁电波导的顶部上，以及最后，IV族和III-V族半导体（即STO、GaAs、AlGaAs、Si、SoI等）的顶部上。然而，这里提出的实验提出了几个技术挑战，需要紧急设备升级。例如，A）现有技术的电光器件需要在小信噪比的条件下并且以可接受的（几十MHz）速度使用i）电动补偿器级和ii）快速检测线进行测试。与此同时，B）将使用iii）带附件的C形框架电磁体和iv）合适的激光检测系统测试各种薄膜和器件的磁光特性。这项申请将补充其他来源的资金。与我们的研究计划有关的好处是双重的：它们将为新的先进技术的发展铺平道路，并将促进高素质人才的培训，符合加拿大工业和社会的需求。

While an increasingly larger amount of data are transported across optical fiber networks by light pulses, and optical computing will soon be a reality, the efficient control of light for communication purposes and all-optical processing has become an extremely important target for photonics engineers. However, such effort necessarily requires the fabrication of several devices in low cost, ultra-compact photonics chips via the monolithic integration of different enabling materials. For this reason, the PIs of this application have established a vigorous research program directed towards the development of a novel thin film technology for applications in photonics and optoelectronics. In particular, they are especially interested in the fabrication of: A) high quality, low loss electro-optic thin films (based on BST, PLZT and CBN) and of: B) high performance magneto-optic thin films (based on Yig and Ce-Yig), to be directly deposited on top of other ferroelectrics waveguides and finally, of Group IV and III-V semiconductors (i.e. STO, GaAs, AlGaAs, Si, SoI, etc). However, the experiments proposed here present several technical challenges that require an urgent equipment upgrading. For example, A) state of the art electro-optic devices need to be tested in conditions of small signal to noise ratio and at an acceptable (several tens of MHz) speed using i) a Motorized compensator stage and ii) a Fast detection line. In parallel, B) the magneto-optic properties of various thin films and devices will be tested using iii) a C-Frame electromagnet with accessories and iv) a suitable laser-detection system. This application will complement funding from other sources. The benefits related to our research programs are twofold: they will pave the way to the development of new advanced technologies and will promote the training of highly qualified personnel, consistently with the needs of Canadian industry and society in general.
