STTR Phase I: Low Voltage Ultrafast Traveling Wave Modulator

该小型企业技术转让（STTR）第一阶段项目将展示一种低电压波导调制器设备，能够以高达40 Gb/s的速度运行。 最终，该设备将能够以高达100 Gb/s的速度运行，驱动电压低至4伏。 用于这些器件的使能技术是用于单晶LiNbO 3薄膜的沉积和图案化的工艺。 LiNbO 3电光器件的全部潜力尚未实现，这是由于在体晶体中通过扩散过程生产它们的限制。 这种开发这种技术的新方法将为新型电光器件开辟道路。这项工作将过渡的外延铌酸锂薄膜技术的商业可行性。 一个电光元件的商业供应商将在这一努力中提供技术指导。 光纤网络正在工业、国防、国内和国际电信中实施。 拟议的技术将使新产品能够为不断增长的光通信网络增加速度，容量和灵活性。 预计到2005年，通过这一努力开发的产品将获得相当大的市场份额。 这项技术将应用于全光计算系统的器件，这些器件也需要LiNbO等非线性材料的单晶薄膜

This Small Business Technology Transfer (STTR) Phase I project will demonstrate a low-voltage waveguide modulator device, capable of operation at speeds up to 40 Gb/s. Ultimately, this device will be capable of operating at speeds up to 100 Gb/s, with drive voltages as low as 4 volts. The enabling technology for these devices is a process for deposition and patterning of single crystal LiNbO3 thin films. The full potential of LiNbO3 electro-optical devices has not been realized, due to the limitations of producing them by diffusion processes in bulk crystals. This new approach to developing this technology will open the way for a new class of electro-optical devices. This work will transition the epitaxial LiNbO3 film technology to commercial viability. A commercial supplier of electro-optical components will collaborate to provide technical guidance during this effort. Fiber optic networks are being implemented in industry, defense and domestic and international telecommunications. The proposed technology will enable new products that will add increased speed, capacity and flexibility to growing optical communications networks. It is anticipated that products developed from this effort will achieve a significant market share by the year 2005. This technology will be applied to devices for all-optical computing systems, which also require single crystal films of non-linear materials such as LiNbO
