Adiabatic Control of Optical Mode Localization in Hybrid Si/III-V Optoelectronic Circuits

这项研究的目的是帮助使光学和电子技术不可避免的合并更接近现实，或者在物质方面，将硅和III V材料结合在一个平台上，用于下一代信息技术。具体地说，它涉及到利用导波光学的一些更微妙的方面来实现对晶体中承载信息的光束的空间控制。智力价值拟议的研究的智力价值是将绝热跃迁的概念扩展到光学和通信领域。多年来，绝热跃迁在物理学中发挥了关键作用，最近又在化学中发挥了关键作用。如果成功，这项拟议的工作可能会对美国光电子业产生重大影响，为就业和福祉做出贡献。广泛影响开展这项拟议的研究需要对研究生进行不同领域的培训，如电磁模式理论和半导体器件制造。从事这项研究的研究生将接触到最先进的理论和制造工具。本科生将通过加州理工大学的暑期本科生研究奖学金计划被纳入该项目。该项目的成果和发现将通过期刊出版物、会议报告和研讨会与科技界分享。

The objective of this research is to help bring closer to reality the inevitable merger of optics and electronics, or in material terms, the union of silicon and III V materials on a platform for the next generation of information technology. Specifically, it involves the use of some of the more subtle aspects of guided wave optics to realize spatial control of information-bearing optical beams in crystals.Intellectual MeritThe intellectual merit of the proposed research is to extend the concept of adiabatic transitions to the optics and communications fields. For years, adiabatic transitions have played a key role in physics and, more recently, chemistry. If successful, the proposed work could have a significant impact on the U.S. optoelectronics industry, contributing to both employment and well-being.Broader ImpactsCarrying out the proposed research requires the training of graduate students in diverse areas such as electromagnetic modal theory and semiconductor device fabrication. Graduate students engaged in this research will be exposed to ahead-of-state-of-the-art theoretical and fabrication tools. Undergraduate students will be incorporated in the project through Caltech's Summer Undergraduate Research Fellowship program. Results and discoveries from this project will be shared with the scientific and technological communities through journal publications, conference presentations, and seminars.
