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.

这个小型企业创新研究(SBIR)第二阶段项目将开发电光光子带隙(EO-PBG)材料和器件。在第一阶段工程中，已经论证了所提出的电光PBG技术的可行性。采用一种低成本、高效率的金属-有机化学液体沉积(MOCLD)技术，成功制备了高质量的La改性PMN-PT(PLMNT)薄膜。PLMNT薄膜具有较大的电光系数。针对器件应用，设计并研究了一种新颖的金属/介质PBG结构。研制了一种电光滤波器/调制器。通过模拟验证了一种用于高效波长调谐的二维光子带隙结构。在第一阶段工作的基础上，新一代可调谐光子带隙材料和器件将推向市场。在商业上，光子带隙材料有望实现对光子流动的类似控制，就像半导体材料中的电子一样，但具有更大的灵活性，因为对光子带隙材料的性质的控制远远超过半导体的电子性质。考虑到半导体材料对社会各个领域的影响，光子带隙材料在21世纪可能会发挥更大的作用，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，如腔体、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、航天和军事领域有很大的应用。
