Dispersion properties of high-contrast grating hollow-core waveguides.
We present unique dispersion characteristics of high-contrast grating (HCG) hollow-core waveguides and show that slow light can be facilitated using internal resonances developing inside the waveguide walls. In addition, we show a fast and precise method of inferring the dispersion information from the waveguide angular reflectivity spectrum.

متن کاملDielectric-lined cylindrical metallic THz waveguides: mode structure and dispersion.
Thin dielectric layers deposited on the inner surface of hollow cylindrical metallic waveguides for Terahertz (THz) waves reduce transmission losses below 1 dB/m. Impact of the dielectric layer on the waveguide dispersion is experimentally investigated by near-field mapping of guided short THz pulses at the input and the output of the waveguide. We obtain dispersion characteristics for the low-...
متن کاملThe Characteristics of Plasma Display with the Cylindrical Hollow Cathode
The newly designed plasma display with the cylindrical hollow cathode has been proposed and investigated to study the relationship between the photoluminous efficiency and the discharge characteristics. The photoluminous efficiency and the discharge characteristics are dependent on the geometry factors of cylindrical hollow cathode and gas pressure in the plasma display. When p (gas pressure) d...
متن کاملRight choice for optical bus interconnect: metallic-hollow-core- waveguides or multimode polymer waveguides?
The performance of metallic-hollow-core-waveguides (MHCWs) and multimode polymer waveguides (MMPWs) are numerically evaluated using ray-tracing method for complex board level optical interconnects systems such as optical bus. Based on an ideal model neglecting the wave-guide surface roughness, we find that MHCWs will provide lower optical loss for small curvature bending waveguides, 45 deg micr...
