SBIR Phase II: Electro-Optic Photonic Bandgap Materials and Devices

这个小企业创新研究（SBIR）二期项目将开发电光光子带隙（EO-PBG）材料和器件。在一期工程中，所提出的电光PBG技术的可行性已经得到了验证。采用独特的金属有机化学液体沉积（mold）技术，成功制备了高质量的la改性PMN-PT (PLMNT) EO薄膜，该工艺成本低，效率高。PLMNT薄膜具有较高的EO系数。设计并研究了一种新型的金属/介电PBG结构。研制了一种电光滤波/调制器。通过仿真证明了二维PBG结构具有有效的波长调谐效果。在第二阶段，基于第一阶段的工作，新一代可调谐PBG材料和器件，如具有最先进性能的滤波器和调制器，将推向市场。商用光子带隙材料有望提供类似于半导体材料中对电子流动的控制，但具有更大的灵活性，因为光子带隙材料的特性比半导体的电子特性更容易控制。鉴于半导体材料对社会各个领域的影响，光子带隙材料可能在21世纪发挥更大的作用，特别是在光通信行业。这种材料不仅可以制成常见的PBG无源元件，如空腔、波导或耦合器，还可以制成有源和动态元件，如高速调制器和可调谐滤波器。这些先进的设备将在工业、太空和军事领域有很大的应用。

This Small Business Innovation Research (SBIR ) Phase II project will develop electro-optic photonic bandgap (EO-PBG) Materials and Devices. During the Phase I project the feasibility of the proposed electro-optic PBG technology has been demonstrated. High quality EO film, La-modified PMN-PT (PLMNT), was successfully deposited using a unique metal-organic chemical liquid deposition (MOCLD) technique, a low cost and efficient manufacturing process. A large EO coefficient was achieved from PLMNT films. An innovative metallic/dielectric PBG structure was designed and studied for device applications. An electro-optic filter/modulator was developed. A two-dimensional PBG structure was demonstrated for efficient wavelength tuning through simulation. In Phase II based on this Phase I work, new generation tunable PBG material and devices, such as filters and modulators with state-of-the-art performance, will be brought to the marketplace.Commercially photonic bandgap materials promise to give similar control of the flow of photons as there is over electrons in a semiconductor material but with even greater flexibility because there is far more control over the properties of photonic bandgap materials than the electronic properties of semiconductors. Given the impact that semiconductor materials have had on every sectors of society, photonic bandgap materials could play an even greater role in the 21st century, particularly in the optical-communications industry. Not only can this material be made into common PBG passive components, such as cavities, waveguides, or couplers, but also the active and dynamic ones, such as high-speed modulator and tunable filters. These advanced devices will have great applications in industrial, space, and military sectors.
