The objective of this program is to transform the observed 2-3 orders-of-magnitude enhancement of two-photon absorption (2PA) in direct bandgap semiconductors using extremely non-degenerate (END) frequencies into photonics device technologies. In the proposed research, radically new device ideas for optical detection and switching will be explored that are made possible by this new discovery. This research is transformative in that the enhanced 2PA results in improved performance, and the types of devices made possible are new and unique. END 2PA greatly decreases the required irradiances needed for such devices. The combination of huge enhancements in 2PA and nonlinear refraction opens up a new realm of possibilities for photonic devices. The intellectual merit is that using END nonlinearities for photonic device applications allows a large reduction in the irradiances needed for nonlinear optical devices. This opens up a new realm of 2PA-based devices as well as great potential for improvement on existing 2-photon based devices. This research will help determine the ultimate limits for these types of nonlinear photonic devices. The broader impacts are, besides funding the training of two Ph.D. students who will benefit from the rigorous graduate curriculum in Optics and Photonics at CREOL, that the large increase in nonlinear response enabled by END configurations has the potential to impact several fields beyond nonlinear optics, including detection and imaging, telecommunications and semiconductor lasers. The PIs also aim to increase the number of students from under-represented groups making use of the many connections and programs offered by our university.

该计划的目的是将观察到的2-3个数量级的双光子吸收（2 PA）在直接带隙半导体中使用极端非简并（END）频率的增强转换为光子器件技术。 在拟议的研究中，将探索用于光学检测和开关的全新设备想法，这一新发现使之成为可能。这项研究是变革性的，因为增强的2 PA导致性能的提高，并且所实现的设备类型是新的和独特的。END 2 PA大大降低了此类设备所需的辐照度。 2 PA和非线性折射的巨大增强的结合为光子器件开辟了一个新的可能性领域。 智力的优点是，使用端的非线性光子器件的应用程序允许在非线性光学器件所需的辐照度的大幅减少。这开辟了基于2 PA的器件的新领域以及改进现有基于2光子的器件的巨大潜力。 这项研究将有助于确定这些类型的非线性光子器件的极限。 更广泛的影响是，除了资助两个博士的培训。对于将从CREOL严格的光学和光子学研究生课程中受益的学生来说，END配置实现的非线性响应的大幅增加有可能影响非线性光学之外的几个领域，包括检测和成像，电信和半导体激光器。 PI还旨在增加来自代表性不足群体的学生人数，利用我们大学提供的许多联系和课程。
