"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."The objective of this research is to realize a card-to-backplane optical interconnection by using an array polymer waveguide data bus and laser diode activated coupler gratings. The significantly increased clock rates of computer central processing units are rapidly outpacing the corresponding electrical motherboard data rates, limited by the severe frequency-dependent electrical interconnections. Optical interconnection using polymer waveguide ribbons is a promising alternative. The proposed use of laser diode activated coupler grating in a UV curable polymer waveguide array can facilitate multi-drop interconnection while preserving optical power when a card is not plugged in. The approach is to develop a light sensitive polymer material that can realize such a coupler grating using low-power diode laser at blue or red wavelength while being UV curable to support soft lithography low-loss waveguide fabrication. A suitable waveguide array will be realized. The coupler gratings and recording hardware will be designed and fabricated to demonstrate the high-speed functionality of the optical interconnection. The intellectual merit of the proposed activity is the exploration of the new card-to-backplane optical interconnection coupler using laser diode activated waveguide grating. Furthermore, a new light sensitive material will be developed. The broader impacts of the proposed research include the development of a new card-to-backplane optical interconnect system for fast computing applications. It is expected to benefit the computing industry, computation science and engineering, high speed test equipment systems, and fiber communication networks. The proposed research will benefit university education and academic graduate research and involve undergraduate senior projects.

“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。“本研究的目的是通过使用阵列聚合物波导数据总线和激光二极管激活耦合器光栅来实现卡到背板的光互连。计算机中央处理单元的显著增加的时钟速率正在快速超过相应的电气主板数据速率，这受到严重的频率相关电气互连的限制。利用聚合物波导带进行光互连是一种很有前途的选择。所提出的在UV可固化聚合物波导阵列中使用激光二极管激活的耦合器光栅可以促进多点互连，同时在卡未插入时保持光功率。该方法是开发一种光敏聚合物材料，可以实现这样的耦合器光栅使用低功率二极管激光器在蓝色或红色波长，同时是UV固化，以支持软光刻低损耗波导制造。将实现合适的波导阵列。耦合器光栅和记录硬件将被设计和制造，以证明光互连的高速功能。拟议活动的智力价值是探索新的卡到背板光互连耦合器使用激光二极管激活波导光栅。此外，还将开发一种新的光敏材料。拟议的研究的更广泛的影响，包括一个新的卡到背板的光学互连系统的快速计算应用的发展。预计将有利于计算行业，计算科学与工程，高速测试设备系统和光纤通信网络。拟议的研究将有利于大学教育和学术研究生研究，并涉及本科生高级项目。
