Terahertz Sensing
Overview
Terahertz (THz) technology has emerged as a rapidly evolving field with immense potential for diverse applications, enabling more practical and efficient sensing systems. One of the key technological breakthroughs is the development of terahertz sources and detectors.
Terahertz waves, located in the electromagnetic spectrum between microwave and infrared radiation, encompass frequencies ranging from 0.1 to 10 THz. This unique range offers several advantages, such as non-ionizing nature, ability to penetrate various materials, and sensitivity to molecular vibrations, making it an ideal tool for imaging and spectroscopy applications.
Terahertz waves interact with matter in distinct ways, providing valuable insights into material properties and composition. As terahertz waves pass through a sample, they can be absorbed or reflected by the molecular vibrations of the sample’s constituents. This absorption and reflection behavior offers valuable information about the sample’s chemical composition, crystalline structure, and physical properties.
Traditional sources, such as molecular gas lasers and free-electron lasers, have limitations regarding cost, size, and complexity.
Quantum Casacade Lasers are the best examples of compact and cost-effective terahertz source. These lasers emit terahertz radiation by utilizing intersubband transitions in semiconductor heterostructures, offering unprecedented control and versatility.
Terahertz detectors have also witnessed remarkable improvements. The emergence of advanced detectors based on technologies like superconducting sensors, field-effect transistors, and photoconductive antennas has significantly enhanced detection efficiency and sensitivity. These advancements have facilitated the development of high-speed and high-resolution terahertz imaging and spectroscopy systems.
