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

0129235 Cerqua-Richardson这项为期三年的美法合作新型光学材料奖由中佛罗里达大学光学学院/CREOL的学生和教职研究人员以及法国波尔多第一大学的研究小组参加。CREOL和波尔多的凯瑟琳·T·瑟卡-理查森、阿尔方斯·舒尔特和蒂埃里·红衣主教将分别领导合作项目。目标是制造和表征用于集成光学应用的硫化物和硫氧化物玻璃及其相关的光波导。硫系玻璃在线性和非线性光学中显示出潜在的应用前景。它们表现出高度的光学非线性，在可见光区域是光敏的，在电信光谱区域是透明的。它们的长期稳定性有限。这项研究将解决目前与非氧化物硫化物玻璃相关的几个限制，并扩展新的硫氧化物玻璃系统的知识。美国研究人员为这项合作带来了块状硫化物材料的加工和光学制造方面的专业知识，以及使用光纤和薄膜的近红外技术的拉曼光谱。法国在块状含氧硫化物材料的合成和表征以及从头计算方面的专业知识补充了这一点。该奖项代表美方向NSF和法国国家科学研究中心(CNRS)提出的联合建议。NSF将支付美国调查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.
