Abstract: Ultrafast THz photonics has demonstrated the capability to create and to measure guided wave and freely propagating subps electrical pulses, which are much shorter than those produced and measured by any other method. THz photonics will be reviewed, starting with the use of photo-conductive switching on lithographically fabricated transmission lines on semiconductor chips. Lithographically fabricated, micron-sized antennas, when photo-conductively driven by subps laser pulses, radiate well into the THz regime. Freely propagating THz-TDS and Waveguide THz-TDS measurements will be presented. Future opportunities in fundamental research and practical applications, including THz communications, will be described.
Keywords: THz-TDS, Quasi-Optics, Photoconductive Switching, and THz Communications.
