    • High-Q terahertz Bragg resonances within a metal parallel plate waveguide 

      Harsha, S. Sree; Laman, N.; Grischkowsky, D. (AIP Publishing, 2009-03-06)
      One-dimensional (1D) Bragg waveguides are demonstrated at terahertz (THz) frequencies. Lithographically made 1D symmetric and asymmetric dielectric gratings on metallized high conductivity Si chips are incorporated within ...

    • THz parallel plate photonic waveguides 

      Bingham, Adam; Zhao, Yuguang; Grischkowsky, D. (AIP Publishing, 2005-07-26)
      We have observed narrowband transmission or rejection in the frequency spectra of THz pulses transmitted through air-spaced parallel plate photonic waveguides. These waveguides have one of the metal plates covered by a ...

    • Underlying terahertz vibrational spectrum of explosives solids 

      Melinger, Joseph S.; Laman, N.; Grischkowsky, D. (AIP Publishing, 2008-07-08)
      Using waveguide terahertz time-domain spectroscopy, we demonstrate the measurement of the underlying terahertz vibrational spectrum of the explosive solids hexahydro-1,3,5-trinitro-1,3,5-triazine, and 2,4,6-trinitrotoluene. ...
