The objective of this program is to develop a family of microphotonic waveguides and devices, based on insights in spatial mode interference, absorption and scattering, that enable new degrees of freedom in photonic device design with ultra-low optical loss. Low loss is achieved using a form of photonic collision avoidance that keeps optical fields away from scatterers using controlled interference. The program will investigate this phenomenon and employ it to develop potentially transformative microphotonic waveguide and device technology, including energy efficient planar waveguide crossing arrays, modulators, and suspended light-force-actuated and thermooptic photonics.The intellectual merit of this research includes the investigation of a newly discovered mode of propagation, low-loss unidirectional Bloch waves, and the design of efficient photonic, electrooptic and optomechanical devices based on their properties to circumvent limitations in state-of-the-art technology. The research will produce a theoretical framework for device design, simulation tools, and proof-of-concept experimental demonstrations.Broader impacts of this work will support national efforts on leadership in science and technology. Proposed devices will enable highly energy efficient optical interconnects uniquely compatible with photonics integration directly with state-of-the-art, unmodified CMOS electronics technology. This may contribute advances in microelectronics and hybrid electronic-photonic technology for high-performance computing, supporting the national interest in large-scale simulation including climate modeling, aerodynamic design, bioengineering and drug design, and financial market simulations. The program will expose undergraduate students to research, and through local visits will excite high school students about engineering with energy efficiency concepts from this research, and more broadly, including solar vehicle racing.

该程序的目的是基于在空间模式干扰，吸收和散射中的见解，开发一个微量波导和设备的家族，从而使光子设备设计的新自由度具有超低光损失。 使用一种光子碰撞的避免形式可实现低损失，从而使光场使用受控的干扰使光场远离散射器。 该计划将调查这种现象并采用IT来开发潜在的转化性微生体波导和设备技术，包括节能的平面波导穿越阵列，调节剂，调节器和悬浮的光能驱动和热的光子学。这项研究的智力优点。基于它们的特性来规避最先进技术的限制。 这项研究将为设备设计，模拟工具和概念验证实验演示提供一个理论框架。这项工作的行为影响将支持国家对科学和技术领导力的努力。 拟议的设备将使高节能的光学互连能够与光子学的唯一兼容，直接与最先进的未修饰的CMOS电子技术集成在一起。 这可能有助于用于高性能计算的微电子和混合电子光功能技术的进步，从而支持大规模模拟的国家利益，包括气候建模，空气动力学设计，生物工程和药物设计以及金融市场模拟。 该计划将使本科生进行研究，并通过本地访问将激发高中生的工程研究，并通过这项研究更广泛地使用能源效率概念，包括太阳能车辆赛车。
