This Small Business Technology Transfer (STTR) Phase I project seeks to develop new types of optical band gaps inside the Brillouin zone in magneto-photonic crystals that will be extremely responsive to external stimuli. These band gaps arise as a result of the hybridization of differently polarized optical modes in a magneto-optic photonic crystal environment. Their formation in functional photonic crystals permits the magnetic control of the crystals' optical response for fast switching applications. The problem to be addressed in this project is the materials requirements for the formation of these magnetically tunable optical band gaps in birefringent non-reciprocal periodic magneto-optic garnet films with large bandwidth. Liquid Phase Epitaxy of thin magneto-optic garnet films on custom substrates will be optimized for all these properties. The films will be characterized by the lithographic and focused-ion-beam patterning implementation of magneto-photonic crystal structures in planar waveguides, which will be used to demonstrate the effectiveness of this approach in achieving the desired optical band gaps.The broader impact/commercial potential will be the development of multi-functional smart materials with commercial applications, as highly sensitive on-chip biosensors, controllable fast optical switches, filters and modulators and magnetic field/current sensors. The detection and analysis of biochemical substances has vast applications in environmental monitoring, biomedical research, healthcare, and homeland security. Optical biosensors constitute an important and powerful tool for the detection of multiple types of analytes ranging from bacteria and bacterial spores to virus and DNA, as well as toxic and non-toxic substances. An interesting feature of the degenerate band gap photonic crystals is the ability to tune a band gap, thus making the structure attractive for the development of optical filters or switches. Optical switching is used in the routing of optical signals for telecommunications and in logic operations. Magneto-optic switching times faster than liquid-crystal, thermal or mechanically based switches are possible. Optical fiber magneto-optic sensors have specific applications in the areas of infrastructure, electric power, automotive, power electronics, aerospace, military, hazardous environments, educational and non-destructive testing.

这个小型企业技术转移（STTR）I阶段项目旨在在磁体晶体中开发新型的光节间隙，这对外部刺激非常有反应。这些带隙是由于磁光光子晶体环境中不同极化光学模式的杂交而产生的。它们在功能光子晶体中的形成允许对快速开关应用的晶体光学响应进行磁控制。该项目中要解决的问题是在双重非重生周期性的磁性磁磁石榴石膜中形成这些磁性可调的光节间隙的材料要求，具有较大的带宽。定制底物上薄磁通石榴石膜的液相外延将针对所有这些特性进行优化。 The films will be characterized by the lithographic and focused-ion-beam patterning implementation of magneto-photonic crystal structures in planar waveguides, which will be used to demonstrate the effectiveness of this approach in achieving the desired optical band gaps.The broader impact/commercial potential will be the development of multi-functional smart materials with commercial applications, as highly sensitive on-chip biosensors, controllable fast optical switches, filters and调节器和磁场/电流传感器。对生化物质的检测和分析在环境监测，生物医学研究，医疗保健和国土安全方面具有广泛的应用。光学生物传感器构成了一种重要而有力的工具，用于检测从细菌和细菌孢子到病毒和DNA以及有毒和无毒物质的多种类型的分析物。退化带隙光子晶体的一个有趣特征是能够调整带隙的能力，从而使结构对光学过滤器或开关的开发有吸引力。光学切换用于电信和逻辑操作的光信号路由。磁化开关时间比液体晶体，热或机械开关更快。光纤磁电通传感器在基础设施，电力，汽车，电力电子，航空航天，军事，危险环境，教育和非破坏性测试领域具有特定的应用。该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。
