项目摘要

Abstract Title: Compact and efficient room temperature operated terahertz emitters for industrial, medical and home security applications. Nontechnical: Terahertz sensing is an enabling technology for noninvasive detection of biological and chemical hazardous agents, cancer detection, detection of mines and explosives, security screening in buildings, airports, and other public space, as well as short-range covert communications in terahertz transmission windows of the atmosphere. Currently available terahertz sources are either bulky or require cryogenic cooling leading to high costs, high complexity, and often low reliability. The proposed novel design concept aims to address most of the deficiencies of the current state-of-the-art terahertz emitter technology. The target device implementation will be similar in terms of the complexity, reliability and size to widely used standard inexpensive near infrared diode lasers. The success of the proposed effort will enable wide deployment of terahertz imaging and spectroscopic sensors for the security screening, medical diagnostics, and industrial monitoring applications. The project requires strongly correlated effort between theory and experiment including extensive modeling, optimization of the device fabrication methodologies as well as detailed characterization and field testing of the novel laser emitters. The research effort is integrated with educational and outreach plans aimed at enhancing education opportunities at the New York and Texas public universities and local communities. Technical: The main goal of the project is the development of high-power diode lasers with built-in resonant nonlinearity for efficient intra-cavity difference frequency generation in the terahertz spectral range. The gain sections based on asymmetric coupled quantum wells utilize the unique band alignment that can be realized in an antimonide material system. Laser modes generated at two closely spaced wavelengths near 2 microns will serve as an intracavity pump field for difference frequency generation. The antimonide-based diode lasers emitting in that spectral region demonstrate some of the lowest threshold current densities ever achieved for semiconductor lasers, excellent temperature stability, and watt level output power, all at room temperature. The expected electrical power input necessary for the proposed device operation with micro to milliwatt terahertz output level will be two to three orders of magnitude lower than those of existing technologies. The proposed research offers experimental and theoretical studies of the fundamental problem of resonant optical nonlinearities in antimonide-based quantum-well systems in a wide range of carrier populations from nondegenerate to highly degenerate. The future development of the proposed devices will include fabrication of widely tunable terahertz emitters as well as integration with silicon photonics. Transfer of the technology to the arsenide or silicon platform will enable epi-side down mounting of large area arrays of the terahertz emitters to scale up the output terahertz power to tens of milliwatt level and perform terahertz beam shaping.

摘要标题：用于工业，医疗和家庭安全应用的紧凑而有效的室温Terahertz发射器。非技术性：Terahertz传感是一种可无创的技术，用于无创的生物学和化学危险剂，癌症检测，矿山和炸药的检测，建筑物，机场和其他公共空间中的安全筛查，以及Terahertz Terahertz传输窗口中大气层的秘密通信。当前可用的Terahertz来源要么是笨重的，要么需要低温冷却，从而导致高成本，高复杂性和通常较低的可靠性。拟议的新型设计概念旨在解决当前最新的Terahertz发射极技术的大多数缺陷。与广泛使用的标准廉价近红外二极管激光器的复杂性，可靠性和大小相似，目标设备的实现将相似。拟议的努力的成功将使Terahertz成像和光谱传感器的广泛部署用于安全筛查，医学诊断和工业监测应用。该项目需要在理论和实验之间密切相关的努力，包括广泛的建模，设备制造方法的优化以及详细的表征和新型激光发射器的现场测试。研究工作与旨在在纽约和得克萨斯州公立大学和当地社区的教育机会的教育和外展计划融合在一起。技术：该项目的主要目标是开发具有内置谐振非线性的高功率二极管激光器，以在Terahertz光谱范围内产生有效的腔内差异频率产生。基于非对称耦合量子井的增益截面利用可以在抗巨剂材料系统中实现的独特带比对。在2微米附近的两个紧密间隔波长下产生的激光模式将作为差异频率产生的腔内泵场。在该光谱区域发射的基于抗氧化二极管激光器表明，半导体激光器，出色的温度稳定性和WATT水平输出功率是有史以来最低的阈值电流密度，这都是在室温下。提议的带有微型到毫克的Terahertz输出水平的设备操作所需的预期电力输入水平将比现有技术低两到三个数量级。拟议的研究提供了基于抗巨胶的量子孔系统在从非排定到高度变性的广泛载体种群中基于抗巨胶的量子孔系统中共振光学非线性的基本问题的实验和理论研究。所提出的设备的未来开发将包括制造广泛可调的Terahertz发射器以及与硅光子学的集成。将技术转移到Arsenide或Silicon平台将使Terahertz发射器的大面积阵列的Epi侧向下安装，以将输出Terahertz功率扩展到数十毫米的水平，并执行Terahertz Beam塑造。
