Terahertz Measurement Approaches for Spectroscopy, Imaging, and Nanophotonics

Optical absorption and ultrafast laser methods for use in the Terahertz spectral region (20-300 micron; 1-700 cm-1) will be described. FTIR and pulsed laser approaches for measuring biomolecular spectra and their theoretical interpretation will first be introduced followed by an overview of the development of reflection imaging for homeland security applications. Time-resolved THz probing of carrier conductivity for solar cell and photon-to-electron energy conversion will also be presented.
