  • Engineering the Propagation Properties of Planar Plasmonic Terahertz Waveguides

    IEEE Journal of Selected Topics in Quantum Electronics

    We recently demonstrated that periodically perforated metal films allow for the creation of complex planar plasmonic terahertz-guided-wave devices. Here, we experimentally examine the effect of changing the geometrical parameters of the periodic perforations on the propagation properties of these devices. These changes allow one to engineer the number of propagating modes and their corresponding frequencies, by varying the metal film thickness and the aperture dimensions, respectively, as well…

    We recently demonstrated that periodically perforated metal films allow for the creation of complex planar plasmonic terahertz-guided-wave devices. Here, we experimentally examine the effect of changing the geometrical parameters of the periodic perforations on the propagation properties of these devices. These changes allow one to engineer the number of propagating modes and their corresponding frequencies, by varying the metal film thickness and the aperture dimensions, respectively, as well as the mode size and associated loss, by varying the aperture periodicity and width. Such information is of critical importance for optimizing the design parameters of these devices.

  • Planar plasmonic terahertz waveguides based on periodically corrugated metal films

    New Journal of Physics

    Research Highlight in Nature Photonics 5, 326–327 (2011)

    We demonstrate that a one-dimensional periodically corrugated metal film can be used to create planar terahertz (THz) waveguides. The periodic corrugation is in the form of rectangular blind holes (i.e. holes that do not completely perforate the metal film) that are fabricated using a multilayer construction. The approach allows for the creation of structures in which the hole depth can be more than four times the hole width. This…

    Research Highlight in Nature Photonics 5, 326–327 (2011)

    We demonstrate that a one-dimensional periodically corrugated metal film can be used to create planar terahertz (THz) waveguides. The periodic corrugation is in the form of rectangular blind holes (i.e. holes that do not completely perforate the metal film) that are fabricated using a multilayer construction. The approach allows for the creation of structures in which the hole depth can be more than four times the hole width. This is necessary to achieve tightly confined THz guided-wave modes. We find that the modes can be modeled using an effective cavity resonance model and that the mode properties depend sensitively on the depth of corrugation. We use numerical simulations to validate the experimental results. We also highlight the differences between simulations that incorporate idealized input parameters and our experimental measurements. Using these data, we fabricate and characterize a Y-splitter to demonstrate the utility of this approach.

  • Planar terahertz waveguides based on complementary split ring resonators

    Optics Express / Optical Society of America

    We experimentally demonstrate planar plasmonic THz waveguides using metal films that are periodically perforated with complementary split ring resonators (CSRRs). The waveguide transmission spectra exhibit numerous transmission resonances. While the geometry is commonly used in developing negative index materials, the excitation geometry used here does not allow for conventional metamaterial response. Instead, we show that all of the observed resonances can be determined from the geometrical…

    We experimentally demonstrate planar plasmonic THz waveguides using metal films that are periodically perforated with complementary split ring resonators (CSRRs). The waveguide transmission spectra exhibit numerous transmission resonances. While the geometry is commonly used in developing negative index materials, the excitation geometry used here does not allow for conventional metamaterial response. Instead, we show that all of the observed resonances can be determined from the geometrical properties of the CSRR apertures. Surprisingly, the Bragg condition does not appear to limit the frequency extent of the observed resonances. The results suggest that metamaterial-inspired geometries may be useful for developing THz guided-wave devices.

  • Planar Terahertz Waveguides Based on Dimpled Metal Films

    Optical Society of America, 2010 Conference on Lasers and Electro-Optics (CLEO) and Quantum Electronics and Laser Science Conference (QELS)

    We demonstrate planar plasmonic THz waveguides based on dimpled metal films. The propagation properties of the guided modes depend upon the geometrical parameters of the of the dimples and can be broadly engineered.
