A novel design-flexible 3D-hollow-waveguide with lateral- and vertical-periodicity has been demonstrated. A high-index-contrast-grating-(HCG), introduced as a lateral-periodicity, provides vertical as well as lateral-optical-confinement. The combined effect of vertical and lateral periodicity results in a low-polarization-dependence.
