Terahertz Generation and Detection

The terahertz gap refers to electromagnetic waves that are in the frequency range of 0.1-10 THz. Terahertz waves have tremendous applications in biomedical imaging and spectroscopy, security, and scientific investigations.

The IOL has introduced a photoconductive terahertz emitter that is based on gallium phosphide semiconductor material that exhibits a transient mobility. This transient mobility allows for high frequency terahertz radiation with low leakage current. Efforts are underway to integrate these developing emitter technologies in biomedical spectroscopic systems.
