This Small Business Innovation Research (SBIR) Phase II project entails the design and building of polarization independent, fiberdized, wavelength selective switches using patent pending EO-waveguide micro-ring technology developed and demonstrated as a result of work carried out under Phase I. The approach is electro-optic, rather than thermo-optic, and operates with negligible power consumption ( 30 microwatts per ring demonstrated in phase I), fast switching ( 100 microseconds demonstrated), larger index modulation (dn 0.01 demonstrated, more possible) and importantly, will enable active polarization dependent loss (PDL) compensation. This will replace thermo-optically tuned ring resonators, which have provided only limited tunability (dn/dt =~ 1.5 x 10-5/oC), slower tuning times ( 3 milliseconds typical), high polarization dependency (no active PDL compensation possible), and are prohibitively power consumptive ( ~~ 0.5 Watts per ring).In the last century the low power transistor replaced the power hungry vacuum tube, thereby ushering in the age of integrated electronics. In a similar fashion, low-power LC-waveguides have the potential to replace high-power thermo-optics (providing a power savings of 10,000), thereby opening up applications and markets for integrated optics. In phase II we will transition our phase I feasibility demonstration into a fully functioning and packaged prototype. 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, which 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. According to Infonetics, a leading market research firm, the ROADM-enabled equipment market size nearly reached $600 million in 2005, tripling earlier forecasts. Over all growth will be determined by affordability and reliability of ROADMs technology, especially within the metro and access space. The technology outlined in this proposal if successful 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）第二阶段项目需要设计和建造偏振独立、光纤化、波长选择开关，使用正在申请专利的eo波导微环技术，该技术是在第一阶段开展的工作中开发和演示的。该方法是电光，而不是热光，并且可以忽略不计的功耗（第一阶段演示的每个环30微瓦）。快速开关（演示了100微秒），更大的折射率调制（演示了0.01，更可能），重要的是，将实现有源极化相关损耗（PDL）补偿。这将取代热光调谐环形谐振器，后者只提供有限的可调性（dn/dt =~ 1.5 x 10-5/oC），较慢的调谐时间（典型3毫秒），高偏振依赖性（无主动PDL补偿可能），并且功耗过高（每环~~ 0.5瓦）。在上个世纪，低功率晶体管取代了耗电的真空管，从而迎来了集成电子学的时代。以类似的方式，低功率lc波导有可能取代高功率热光学（提供10,000的电力节省），从而为集成光学打开应用和市场。在第二阶段，我们将把第一阶段的可行性演示转变为一个功能齐全的包装原型。随着计算能力和带宽的持续增长（例如，流媒体），将需要低成本的光电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。典型的部署系统通过读取输入的光信号并将其转换为电信号，然后将其路由。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。根据领先的市场研究公司Infonetics的数据，2005年roadm设备市场规模接近6亿美元，是之前预测的三倍。总体而言，增长将取决于roadm技术的可负担性和可靠性，特别是在地铁和接入空间内。本提案中概述的技术如果成功，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。
