CAREER: Optical Forces in Integrated Microphotonic DevicesPI: Michelle L. Povinelli, University of Southern CaliforniaMicrophotonic devices, such as photonic crystals and microresonators, control light on the sub-wavelength scale. Large-scale integration on semiconductor chips will enable all-optical circuits capable of complex information processing. To achieve this goal, mechanisms for tuning, adapting, and reconfiguring individual devices are needed. The proposed work will use optical forces for this purpose. Preliminary results have shown that light can be used to pull two parallel cantilevers together or push them apart. This effect will be used to envision new optical devices whose properties can be controlled all-optically. Electromagnetic simulations will be used to calculate optical forces in lithographically-fabricated structures such as coupled waveguide cantilevers and photonic crystal slabs.Intellectual Merit: The proposed research will establish a new mechanism for positioning and control on the nanoscale. The results are expected to have broad impact in microphotonics, integrated optics, quantum optomechanics, and optical trapping. The work will benefit from cross-fertilization of ideas with the MEMS community: optical forces provide an alternative actuation mechanism to traditional electrostatic approaches and will result in unique application niches. Broader Impact: The proposed work includes integrated research and educational activities that will impact the scientific research, USC, and Los Angeles communities. The PI will give lectures on engineering careers to groups of female and minority students. The PI and her research group will also work with the USC Center for Engineering Diversity to develop two programs for educationally-disadvantaged K-12 students: interactive optics demos and classroom talks by USC undergraduates that relate electrical engineering to everyday life.

职业：集成微光子器件中的光学力PI：Michelle L。Povinelli，南加州大学微光子器件，如光子晶体和微谐振器，在亚波长尺度上控制光。半导体芯片的大规模集成将使全光电路能够进行复杂的信息处理。为了实现这一目标，需要用于调整、适配和重新配置各个设备的机制。拟议的工作将使用光学力用于此目的。初步结果表明，光可以用来将两个平行的杠杆拉在一起或将它们推开。这种效应将被用来设想新的光学器件，其属性可以控制全光学。电磁模拟将被用来计算光刻制造的结构，如耦合波导杠杆和光子晶体slaps.Intellectual优点：拟议的研究将建立一个新的机制，定位和控制的纳米尺度。这些结果有望在微光子学、集成光学、量子光学力学和光阱等领域产生广泛的影响。这项工作将受益于与MEMS社区的思想交流：光学力提供了一种替代传统静电方法的驱动机制，并将产生独特的应用领域。更广泛的影响：拟议的工作包括综合研究和教育活动，将影响科学研究，南加州大学和洛杉矶社区。PI将为女性和少数民族学生团体举办工程职业讲座。PI和她的研究小组还将与南加州大学工程多样性中心合作，为教育弱势的K-12学生开发两个项目：交互式光学演示和南加州大学本科生的课堂演讲，将电气工程与日常生活联系起来。
