This Small Business Innovation Research (SBIR) Phase I project entails the construction of voltage tunable micro-ring, optical waveguide resonators. The devices will exploit novel waveguide electro-optic technology capable of a large index modulation (currently ?n .02 with the potential for ?n .05). This large index modulation enables micro-ring structure with widely tunable resonances (10 nm, and potentially up to 100 nm), fast tuning times ( 1 millisecond), low optical losses, and extremely low power consumption ( 0.05 milliwatts per ring). Furthermore, innovative electrode geometry provides polarization independent operation. These voltage tuned micro-rings will replace thermo-optically tuned ring resonators, which have provided only limited tunability ( dn/dt ~~ 1.5~~10-5/oC), have high polarization dependency, and have historically been prohibitively power consumptive ( ~~ 0.5 Watts per ring). Finally, the voltage tuned micro-ring resonators will enable a low cost, ultra-compact reconfigurable optical add/drop, which is the critical component in a wide array of high-bandwidth electro-optical communications systems. As computing power and bandwidth continue to grow (e.g., streaming media), low-cost electro optical filtering and switching systems will be required to satisfy pending fiber-to-the-home and "last mile" deployment needs. Since 2002, United States and European deployment of long-haul dense wavelength division multiplexing (DWDM) systems have been almost entirely constructed from reconfigurable optical add-drop multiplexers (ROADM). A typical deployed system works by reading incoming optical signals and converting them to electrical signals that can then be routed. Conversion back to optical is performed by an array of tunable lasers. This brute force method, while providing useful performance, is cost prohibitive for small network deployment. The current total addressable world market for ROADMs technology is around $3.46 billion with double digit growth expected through 2010. Over all growth will be determined by affordability and reliability of ROADMs technology. The technology outlined in this proposal will contribute a new and inherently agile all optical solution by reducing cost while maintaining performance and reliability. In addition to ROADMs, the voltage tunable micro-rings will enable a wide array of useful devices, ranging from spectral filters, to optical cross-connects, to routers, to name only a few.

这个小企业创新研究（SBIR）第一阶段项目需要建设电压可调微环，光波导谐振器。该设备将利用新型波导电光技术，能够进行大折射率调制(目前？n。有潜力的？n . 05)。这种大折射率调制使微环结构具有广泛可调谐的共振（10 nm，甚至可能高达100 nm），快速调谐时间（1毫秒），低光学损耗和极低功耗（每环0.05毫瓦）。此外，创新的电极几何结构提供了与极化无关的操作。这些电压调谐微环将取代热光调谐环形谐振器，后者只能提供有限的可调性（dn/dt ~~ 1.5~~10-5/oC），具有高度的偏振依赖性，并且历史上功耗过高（每环~~ 0.5瓦）。最后，电压调谐微环谐振器将实现低成本，超紧凑的可重构光加/丢，这是各种高带宽电光通信系统的关键组件。随着计算能力和带宽的持续增长（例如，流媒体），将需要低成本的电光滤波和交换系统来满足即将到来的光纤到户和“最后一英里”部署需求。自2002年以来，美国和欧洲部署的长途密集波分复用（DWDM）系统几乎完全由可重构的光加丢复用器（ROADM）构成。一个典型的部署系统的工作原理是读取输入的光信号，并将其转换为可以路由的电信号。转换回光学是由一组可调谐激光器完成的。这种暴力破解方法虽然提供了有用的性能，但对于小型网络部署来说成本过高。目前roadm技术的全球潜在市场总额约为34.6亿美元，预计到2010年将有两位数的增长。总体而言，增长将取决于roadm技术的可负担性和可靠性。本提案中概述的技术将通过在保持性能和可靠性的同时降低成本，贡献一种新的、固有的敏捷全光解决方案。除了roadm之外，电压可调微环将使一系列有用的设备成为可能，从光谱滤波器到光交叉连接到路由器，仅举几例。
