Intellectual Merit:This project will develop a new class of interband cascade lasers based on plasmon-waveguides. The plasmon-waveguide lasers will be much less demanding in the growth of device structures and have significantly enhanced thermal dissipation compared to current interband cascade lasers that use superlattices as cladding layers. This will result in efficient cw operation at a wide range of wavelengths and at higher temperatures. The success of this research project will, not only realize efficient, plasmon-waveguide interband cascade lasers with low power consumption, it will advance the understanding of how plasmon-waveguides can significantly improve the device performance of interband diode lasers. Efficient, plasmon-waveguide interband cascade lasers will greatly enhance the capabilities of mid-infrared laser instruments, which will benefit many useful applications, especially where mid-infrared systems must be operated with batteries and energy cost/availability is a concern. Broader Impacts: This project will generate new cutting-edge knowledge toward improved design and understanding of quantum semiconductor structures and devices. The realization of energy-efficient plasmon-waveguide interband cascade lasers in the mid-infrared wavelength region will have significant impact on biomedical, industrial, earth science, space exploration, defense and homeland security applications. This project will offer graduate and undergraduate students at the University of Oklahoma unique opportunities to pursue education, training and research in multidisciplinary topics (materials science, quantum engineering, photonics, and device fabrication). This project will also enhance Oklahoma?s infrastructure for science and technology development and increase the opportunities of students from under-represented regions in science and engineering. The lasers produced in this project will be eye-safe and used in education (even research) projects by selected K-12 schools. This project will promote the participation of faculty and students in statewide educational outreach activities.

智力优势：该项目将开发一种新的基于等离子体波导的带间级联激光器。 等离子体激元波导激光器在器件结构的生长中的要求要低得多，并且与使用超晶格作为包覆层的当前带间级联激光器相比，具有显著增强的散热。 这将导致在宽波长范围和更高温度下的高效连续波操作。 该研究项目的成功不仅将实现低功耗的高效等离子体激元波导带间级联激光器，还将促进对等离子体激元波导如何显著改善带间二极管激光器器件性能的理解。 高效的等离子体激元波导带间级联激光器将大大增强中红外激光仪器的能力，这将有利于许多有用的应用，特别是在中红外系统必须使用电池操作并且能源成本/可用性是一个问题的情况下。 更广泛的影响：该项目将产生新的尖端知识，以改进量子半导体结构和器件的设计和理解。 在中红外波段实现高能效的等离子体激元-波导带间级联激光器将对生物医学、工业、地球科学、空间探索、国防和国土安全等领域产生重大影响。 该项目将为俄克拉荷马州大学的研究生和本科生提供独特的机会，在多学科主题（材料科学，量子工程，光子学和器件制造）中进行教育，培训和研究。 这个项目也将提高俄克拉荷马州？这将有助于加强科学和技术发展的基础设施，并增加来自代表性不足地区的学生在科学和工程领域的机会。 该项目生产的激光器将对眼睛安全，并用于选定的K-12学校的教育（甚至研究）项目。该项目将促进教师和学生参与全州范围的教育推广活动。
