STTR Phase I: Low Voltage Ultrafast Traveling Wave Modulator

这个小型企业技术转让第一阶段项目将展示一种低压波导调制器设备，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。这些器件的使能技术是单晶LiNbO_3薄膜的沉积和图案化过程。LiNbO_3电光器件的全部潜力还没有完全实现，这是由于在大块晶体中通过扩散过程生产它们的局限性。这种开发这项技术的新方法将为新类别的光电设备开辟道路。这项工作将把LiNbO_3外延薄膜技术转化为商业可行性。一家电光组件的商业供应商将在这一努力期间合作提供技术指导。光纤网络正在工业、国防和国内外电信中实施。拟议的技术将使新产品成为可能，这些产品将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设备，这些设备也需要非线性材料的单晶膜，如LiNbO

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
