Development of a Laser Driven Terahertz System to Study Materials and Devices, and Student Training

加州大学圣巴巴拉分校获得材料研究项目仪器奖后，将开发激光驱动太赫兹系统，为材料、材料结构和设备的高分辨率线性太赫兹光谱提供新的研究仪器。该仪器将提供高达~1太赫兹(THz)的微瓦可调辐射。在~1太赫兹以上，功率将大大减少，但对材料和材料结构的线性、高分辨率光谱来说绰绰有余。该系统的频率高达1太赫兹，采用适当的激励和采样方法，还将用于测试超出现有网络分析仪能力的最先进电子设备的性能。同时，该系统将为探索利用光电导和非线性极化率产生太赫兹辐射的光学差频新材料和新器件提供试验台。这一新仪器的研究和开发将为博士后研究人员以及物理学、材料科学和固态电子学的研究生和本科生提供跨学科的教育和培训。%获得材料研究仪器项目的这一奖项后，加州大学圣巴巴拉分校将开发一种激光驱动太赫兹系统，该系统将为材料、材料结构和器件的高分辨率线性太赫兹光谱提供新的研究仪器。电磁频谱中的太赫兹部分，从100 GHz到10太赫兹，是科学丰富的，但技术相对贫乏。激光驱动太赫兹系统将为材料、材料结构和设备的高分辨率线性太赫兹光谱提供新的研究仪器。这一新仪器的研发将为致力于该项目的博士后研究人员以及将在物理、材料科学和固态电子领域使用该仪器的研究生和本科生研究人员提供跨学科的教育和培训。该仪器将提供高达~1太赫兹(THz)的微瓦可调辐射。在~1太赫兹以上，功率将大大减少，但对材料和材料结构的线性、高分辨率光谱来说绰绰有余。

With this award from Instrumentation for Materials Research Program the University of California, Santa Barbara, will develop a Laser Driven Terahertz System which will provide new research instrumentation for high-resolution linear terahertz spectroscopy of materials, material structures, and devices. The instrument will deliver microwatts of tunable radiation up to ~1 terahertz (THz). Above ~1 terahertz the power will be substantially less but more than adequate for linear, high-resolution spectroscopy of materials and material structures. Up to 1 terahertz, with suitable methods of excitation and sampling, the system will also be used to test the performance of state-of-the-art electronics at frequencies that exceed the capability of existing network analyzers. At the same time, the system will provide a test bed to explore new non-linear materials and devices for optical difference frequency generation of terahertz radiation by photoconductivity and non-linear susceptibility. The research and development of this new instrument will provide interdisciplinary education and training for postdoctoral researcher and to graduate and undergraduate students in physics, materials science and solid state electronics.%%%With this award from Instrumentation for Materials Research program the University of California Santa Barbara will develop a Laser Driven Terahertz System which will provide new research instrumentation for high-resolution linear terahertz spectroscopy of materials, material structures, and devices. The terahertz part of electromagnetic spectrum, from 100 GHz to 10 THz, is science rich but relatively technology poor. The Laser Driven Terahertz System will provide new research instrumentation for high-resolution linear terahertz spectroscopy of materials, material structures, and devices. The research and development of this new instrument will provide interdisciplinary education and training for the post-doctoral researcher committed to the project and to graduate student and undergraduate researchers who will use the instrument in physics, materials science and solid state electronics. The instrument will deliver microwatts of tunable radiation up to ~1 terahertz (THz). Above ~1 terahertz the power will be substantially less but more than adequate for linear, high-resolution spectroscopy of materials and material structures.
