Temperature Insensitive Silicon Photonics

该提案的目的是研究新的紧凑的几何形状，克服了传统的硅纳米光子学的温度敏感性，使未来的计算系统，具有高带宽和低power.Intellectual优点：我们建议通过定制限制在硅波导的程度来控制光子结构的热漂移。我们的目标是实现结构，自我补偿的温度效应的基础上，这种波导与不同的热漂移。我们的初步工作表明，定制的干涉结构的热光漂移的可能性。这种热稳定技术是完全被动的，并且与当前的微电子制造工艺完全兼容。我们建议使用这种方法来演示一个40 GHz的WDM调制器系统稳定的temperature.Broader影响：在这项研究中获得的基本知识对温度不敏感的设备，特别是温度不敏感的调制器也适用于其他新颖的光子结构，如光路由器，开关和过滤器以及其他光学材料系统，如玻璃基化合物。我们建议开发一个教育计划，让学生接触光子学作为一个跨学科的领域，并加强本科和研究生电气和计算机工程课程在光子学领域。将为本科生和研究生开发一个跨学科的研讨会系列，并将涵盖与光子学相关的研究领域，如：光子材料，生物医学应用和光学计算。我们还建议在康奈尔大学的电子和计算机工程课程中引入光子学的新学科，以包括活跃的研究领域。

The objective of the proposal is to investigate novel compact geometries that overcome the traditional temperature sensitivity of Si nanophotonics enabling future computing systems that with high bandwidth and low power.Intellectual Merit: We propose to control the thermal drift of photonic structures by tailoring the degree of confinement in silicon waveguides. We aim to achieve structures that self compensate for temperature effects based on such waveguides with dissimilar thermal drifts. Our preliminary work shows the possibility to tailor the thermo-optic drift of an interferometric structure. This technique of thermal stabilization is completely passive and fully compatible with current microelectronics fabrication processing. We propose to use this approach for demonstrating a 40 GHz WDM modulator system stable with temperature.Broader Impacts:The fundamental knowledge gained in this research on temperature insensitive devices and in particular temperature insensitive modulators is also applicable to other novel photonic structures such as optical routers, switches and filters as well as other optical materials system such as glass-based compounds. We propose to develop an educational program for exposing students to photonics as an interdisciplinary area and enhancing the undergraduate and graduate Electrical and Computer Engineering curriculum in the area of photonics. An interdisciplinary seminar series will be developed for undergraduate and graduate students and will cover research areas related to photonics such as: photonic materials, biomedical applications, and optical computing. We also propose to introduce novel subjects of photonics in courses of the electrical and computer engineering in Cornell university to include active research areas.
