This Small Business Innovation Research (SBIR) Phase II research project addresses the device and market opportunity for thick magnetooptic garnet Faraday rotator films with planar anisotropy to be operated in the near infrared. Magnetic and electromagnetic field sensors could be developed at a variety of near-infrared wavelengths including the 800 nm, 1310 nm and 1550 nm bands. These sensors can be made much less expensively, in much smaller sizes and with much less weight than current technologies such as current transformers. They have a potential for immediate impact in reliability of electric power distribution through failure anticipation and prevention and conservation of electric power through monitoring and control. Planar materials have much higher switching speeds than conventional perpendicular Faraday rotators and as such would permit a magnetooptical approach to packet switching. Such films are an innovative solution to device problems that require high-speed, continuously-varying polarization rotation with applied field. The project will work on improving properties and performance of such thick planar films and incorporate them into devices. Specific materials tasks are directed to improving sensitivity, linearity and temperature range of operation.If successful these sensors will have applications such as wheel and turbine rotation, electric power distribution, monitoring, metering and control, and battlefield sensors. The electric power application in particular has potential to revolutionize catastrophic failure prevention in the power grid and reduce power costs at a variety of levels by enabling autonomous reconfiguration. The lack of electrical connectors in fiber optic sensors for explosive, flammable and high-voltage environments represent a significant improvement in safety. New photonic devices not currently realizable will be enabled for telecommunications and military applications such as variable optical attenuators, polarization controllers and increased speed magnetooptic switches. Photonic devices include polarization controllers, variable optical attenuators, switches and new innovative devices. Smart ships and buildings would find utility both for conservation and efficiency.

这项小型企业创新研究（SBIR）第二阶段研究项目介绍了带有平面各向异性的厚磁场石榴石旋转膜的设备和市场机会，该膜将在近红外运营。磁场和电磁场传感器可以在多种近红外波长（包括800 nm，1310 nm和1550 nm频段）上开发。这些传感器的额外尺寸要小得多，并且重量要比当前的技术（例如当前的变压器）少得多。通过监测和控制，它们有可能立即影响电力发电的可靠性，并预防电力和电力保护。平面材料的开关速度比传统的垂直法拉第旋转器高得多，因此，可以采用磁置方法来切换。此类膜是针对需要高速，连续变化的极化旋转的设备问题的创新解决方案。该项目将致力于改善这种厚的平面膜的性能和性能，并将其纳入设备。特定的材料任务旨在提高灵敏度，线性和温度范围的操作范围。如果成功的传感器将具有诸如车轮和涡轮机旋转，电动发电，监控，计量和控制以及战场传感器等应用。 尤其是电力应用有可能通过实现自主重新配置来彻底改变电网中的灾难性故障预防，并在各种级别降低电力成本。光纤传感器中缺乏用于爆炸性，易燃和高压环境的电气连接器代表了安全性的显着改善。当前尚不可实现的新光子设备将用于电信和军事应用，例如可变的光衰减器，极化控制器和增加速度磁盘开关。光子设备包括极化控制器，可变的光衰减器，开关和新的创新设备。智能船只和建筑物都可以找到效用以进行保护和效率。
