U.S. - France Cooperative Research: Sulfide and Oxysulfide Glasses - Novel Optical Materials for Integrated Optics

这项为期三年的奖项旨在表彰美法在新型光学材料领域的合作，参与者包括中佛罗里达大学光学/CREOL学院的学生和教师研究人员以及法国波尔多第一大学的研究小组。CREOL和Bordeaux的Kathleen T. Cerqua-Richardson、Alfons Schulte和Thierry Cardinal将分别领导该合作项目。目标是制造和表征硫系化物和硫化氧玻璃及其相关的集成光学波导应用。硫系玻璃在线性和非线性光学中已显示出潜在的应用前景。它们具有高度的光学非线性，在可见光区具有光敏性，在通信光谱区具有透明性。它们的长期稳定性有限。该研究将解决目前与非氧化物硫化物玻璃相关的几个限制，并扩展新的硫化物氧化玻璃系统的知识。美国研究人员为此次合作带来了大块硫族化合物材料的加工和光学制造方面的专业知识，使用近红外技术对纤维和薄膜进行拉曼光谱分析。这是由法国在合成和表征大块氧化硫化物材料和从头计算方面的专业知识补充。该奖项代表了美国方面向美国国家科学基金会和法国国家科学研究中心（CNRS）联合提出的建议。美国国家科学基金会将支付美国研究人员和研究生的旅费和生活费。CNRS将支持法国研究人员和研究生访问美国。

0129235Cerqua-RichardsonThis three-year award for U.S.-France collaboration in novel optical materials involves students and faculty researchers at the University of Central Florida's School of Optics/CREOL and research groups at the University of Bordeaux I in France. Kathleen T. Cerqua-Richardson, Alfons Schulte, and Thierry Cardinal at CREOL and Bordeaux respectively will lead the collaborative program. The goal is to fabricate and characterize chalcogenide and oxysulfide glasses and their related waveguides for integrated optic applications. Chalcogenide glasses have shown potential for use in linear and nonlinear optics. They exhibit high optical nonlinearities, are photosensitive in the visible region and transparent in the telecommunication spectral region. They suffer from limited long-term stability. The research will address several current limitations associated with non-oxide chalcogenide glasses and extend knowledge in new oxysulfide glass systems. The US researchers bring to this collaboration expertise in processing and optical fabrication of bulk chalcogenide materials, Raman spectroscopy using near infrared techniques for fiber and films. This is complemented by French expertise in the synthesis and characterization of bulk oxysulfide materials and ab initio calculations. This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigators and graduate student. CNRS will support the visits of the French researchers and graduate students to the United States.
