Studies in Optical-Microwave Interaction and Fiberoptic Sensors

该奖项支持由德雷塞尔大学微波光波工程中心（CMLE）的Peter Herczfeld和里约热内卢天主教大学电信研究中心（CETUC）的Alvaro De Salles进行的电子工程合作研究。合作研究的科学领域是半导体器件和光纤传感器中高频电磁波与光波的相互作用。德雷克塞尔大学有一个活跃的项目，研究光波和高频电磁波在半导体材料和器件中的相互作用。这些研究包括带外腔半导体激光器的非线性行为和单片微波集成电路（MMIC）元件在光学照明下的性能。此外，CMLE在光纤传感器设备方面也有一个活跃的项目。在巴西，CETUC在相同的技术领域建立了完善的项目。在CETUC，用于巴西电力工业的传感器的研究正在取得进展。提出的合作工作将适应在CMLE开发的电压和电流传感方法，这是CETUC感兴趣的，并扩展对光纤模态耦合的基本理解。计划进行实验和分析研究。在此之前，中欧交通大学和CMLE的研究人员之间的联系包括交换科学信息和样品设备，交换研究生，访问和讲座，以及在科学论文和书籍方面的合作。这项工作是以前一次非正式合作的成果。拟议的研究将是目前活动的自然延伸，并将强调这两个合作伙伴在上述研究主题的基本和一般方面的重叠利益。

This award supports cooperative research in electrical engineering to be conducted by Peter Herczfeld of the Center for Microwave-Lightwave Engineering (CMLE) at Drexel University and Alvaro De Salles of the Center for Studies in Telecommunications (CETUC) of the Catholic University in Rio de Janeiro. The scientific areas of the cooperative research are the interaction of high frequency electromagnetic and light waves in semiconductor devices and fiberoptic sensors. Drexel has an active program studying the interaction of lightwaves and high-frequency electromagnetic waves in semi- conducting materials and devices. These studies include the nonlinear behavior of semi-conductor lasers with external cavities and the performance of monolithic microwave integrated circuit (MMIC) components under optical illumination. In addition CMLE has an active program in fiberoptic sensor devices. In Brazil, CETUC has well established programs in the same technical areas. At CETUC, research is progressing on sensors for the Brazilian power industry. The proposed cooperative work will adapt the methods developed at CMLE for voltage and current sensing, which is of interest to CETUC, and expand on the basic understanding of modal coupling in fibers. Both experimental and analytic research are planned. Previous contacts between the researchers at CETUC and CMLE have included exchange of scientific information and sample devices, exchange of graduate students, visits and lectures at each institution and collaboration on scientific articles and books. This work represents the culmination of a previous informal cooperation. The proposed research will be a natural extension of present activities and will emphasize the overlapping interests of these two collaborating partners in the fundamental, generic aspect of the research topics identified above.
