THz Photonics Technology and Its Applications

Terahertz (THz) radiation, which occupies a large portion of the electromagnetic spectrum between the mid-infrared and microwave bands, offers innovative imaging and sensing technologies that can provide information, which may not be available through conventional methods (i.e. microwave and X-ray techniques.) As THz wave (T-ray) technology improves, we believe new THz wave sensing and imaging capabilities will impact a range of interdisciplinary fields, including: communications, imaging, medical diagnosis, health monitoring, environmental control, and chemical and biological identification. This is particularly crucial for identifying terrorist threats in homeland security (three to five years), and medical diagnosis or even clinical treatment in biomedical applications (five to ten years).
