Photonics Devices Based on Two-Photon Absorption: Collaborative Research with University of Auckland on Materials Processing and Device

在这个项目中，来自新墨西哥大学（UNM）的研究人员将与奥克兰大学（奥克兰/新西兰）合作，进行与先进超快双光子吸收（TPA）半导体器件量子工程相关的基础研究，目的是阐明导致光波通信系统中超快TPA器件优化的所有关键步骤。具体的技术目标包括设计和制造新的量子限制结构，测量TPA系数的精确大小，演示将导致TPA光子器件有效带宽增加的新处理方法，以及这些器件的详细线性和非线性光谱研究。半导体中的双光子吸收领域是两国（美国/新西兰）共同感兴趣的领域，因为在这一光学基础领域的研究为培养/教育未来的科学家和工程师提供了一个极好的机会，除了它在超快光通信中的适用性之外，还可以专门从事光子学。这种合作效应将使奥克兰大学的研究团队受益，奥克兰大学在半导体非线性光学的基本特性方面的专业知识，以及关于量子限制结构（量子阱和量子点）和相关器件制造的材料研究和处理问题。

Specific technical objectives include the design and fabrication of new quantum-confined structures, measurement of the precise magnitudes of the TPA coefficient, demonstration of novel processingmethods that will lead to an increase in the effective bandwidth of TPA photonic devices, and detailed linear and non-linear spectroscopic studies of these devices.The field of two photon absorption in semiconductors is of mutual interest to both countries (US/NZ), as investigations in this basic area of optics provides an excellent opportunity for the training/education of future scientists and engineers specializing in photonics, in addition to its applicability in ultrafast optical communications. This collaborative effect will benefit the UNM researcher team through Auckland's expertise in fundamental properties of nonlinear optics in semiconductors, and in materials research & processing issues regarding growth of quantum-confined structures (quantum wells & quantum dots) and related device fabrication.
