We show that hollow dielectric-coated metallic waveguides exhibit ultrabroadband transmission and controlled anomalous dispersion in the visible, UV, and VUV range even at high gas pressures. Using the transfer-matrix method we predict that the losses can be significantly reduced in such waveguides, which allows the use of small radii in the range of 10-25 microm. The resulting significant enhancement of the waveguide contribution to dispersion facilitates phase-matching for nonlinear processes with higher efficiencies.
