Design and Implementation of Efficient Terahertz Waveguides
Supervisory Committee Dr. Thomas Edward Darcie, (Department of Electrical and Computer Engineering) Supervisor Dr. Jens Bornemann, (Department of Electrical and Computer Engineering) Departmental Member Dr. Colin Bradley, (Department of Mechanical engineering) Outside Member In this thesis, novel broadband waveguides capable of operating at terahertz (THz) frequencies are introduced. We explore...
متن کاملEfficient Chemical Sensing by Coupled Slot SOI Waveguides
A guided-wave chemical sensor for the detection of environmental pollutants or biochemical substances has been designed. The sensor is based on an asymmetric directional coupler employing slot optical waveguides. The use of a nanometer guiding structure where optical mode is confined in a low-index region permits a very compact sensor (device area about 1200 μm(2)) to be realized, having the mi...
متن کاملTerahertz composite right-left handed transmission-line metamaterial waveguides
We report terahertz metamaterial waveguides based on the concept of composite right/left-handed transmission-lines. The waveguides are implemented in a metal-insulator-metal geometry fabricated with spin-coated Benzocyclobutene and contact photolithography. Angle-resolved reflection spectroscopy shows strong resonant absorption features corresponding to both right-handed and left-handed (backwa...
متن کاملNonlinear plasmonic slot waveguides.
We study nonlinear modes in a subwavelength slot waveguide created by a nonlinear dielectric slab sandwiched between two metals. We present the dispersion diagrams of the families of nonlinear guided modes and reveal that the symmetric mode undergoes the symmetry-breaking bifurcation and becomes primarily localized near one of the interfaces. We also find that the antisymmetric mode may split i...
متن کاملLow-loss terahertz ribbon waveguides.
The submillimeter wave or terahertz (THz) band (1 mm-100 microm) is one of the last unexplored frontiers in the electromagnetic spectrum. A major stumbling block hampering instrument deployment in this frequency regime is the lack of a low-loss guiding structure equivalent to the optical fiber that is so prevalent at the visible wavelengths. The presence of strong inherent vibrational absorptio...
