High Density Three-Dimensional Optical Data Storage: High Fidelity Two-Photon Polymeric Photochromic WORMKevin D. BelfieldDepartment of Chemistry and CREOL, College of Optics and PhotonicsUniversity of Central FloridaIntellectual merit: The vast number of advantages associated with multiphoton absorption-induced processes is fast propelling multiphoton absorbing materials and processes to the forefront of several important fields, and provide compelling rationale for extensive research and educational training in this field. However, the potential of two-photon absorption (2PA) for optical data storage has yet to overcome some serious materials limitations, and it has been recognized that the 2PA and properties need to be increased in order for practical multiphoton absorption-based 3D optical data storage and processing media to be realized. The proposed research will develop new, highly stable and sensitive two-photon absorbing photochromic materials and a non-destructive readout method for 3D optical data storage. With knowledge gained in this research, the development of high fidelity photochromic 3D optical data storage materials and processes will result.Broader impacts: The approach taken in this program involves a multi-disciplinary laboratory in which undergraduate students, graduate students, and postdoctoral researchers receive cross-disciplinary training in photonic materials synthesis and characterization, photophysics, absorption and luminescence spectroscopy, laser systems, and optical science. It is believed that such an approach will afford a fundamental understanding of two-photon absorption-based photochromic processes and provide the tenets for developing materials for applications for the important field of 3D optical data storage. Broad influence on society may result by increasing storage density, impacting essentially all aspects of today's economy spanning from data storage and computer networks to display technology. Students will be engaged in interdisciplinary research training that will position them to make significant scientific and technical contributions in the photonic materials fields. This project will provide research and educational opportunities for undergraduate and graduate students, as well as postdoctoral researchers, including those from traditionally underrepresented groups, facilitating the preparation of a highly skilled and diverse workforce.

高密度三维光学数据存储：高保真双光子聚合物光致变色WORMKevin D.Belfield中央佛罗里达大学光学与光子学学院化学与CREOL系智力优势：与多光子吸收相关的大量优势正在迅速将多光子吸收材料和方法推向几个重要领域的前沿，并为该领域的广泛研究和教育培训提供了令人信服的理论基础。然而，双光子吸收(2PA)用于光学数据存储的潜力还没有克服一些严重的材料限制，人们已经认识到，为了实现实用的基于多光子吸收的三维光学数据存储和处理介质，需要提高2PA和性能。这项研究将开发新的、高度稳定和灵敏的双光子吸收光致变色材料和一种用于三维光学数据存储的无损读出方法。随着这项研究获得的知识，高保真光致变色3D光学数据存储材料和工艺的开发将产生深远的影响：该项目采取的方法包括一个多学科实验室，本科生、研究生和博士后研究人员在其中接受光子材料合成和表征、光物理、吸收和发光光谱、激光系统和光学科学的跨学科培训。人们认为，这种方法将使人们对基于双光子吸收的光致变色过程有一个基本的了解，并为开发应用于3D光学数据存储这一重要领域的材料提供原理。增加存储密度可能会对社会产生广泛的影响，从数据存储、计算机网络到显示技术，基本上影响到当今经济的方方面面。学生将从事跨学科的研究培训，这将使他们能够在光子材料领域做出重大的科学和技术贡献。该项目将为本科生和研究生以及博士后研究人员提供研究和教育机会，包括那些来自传统上代表性不足的群体的研究人员，以促进培养一支高技能和多样化的劳动力队伍。
