Novel three-dimensional hollow-core waveguide using high-contrast sub-wavelength grating

A novel hollow-core waveguide using high-contrast sub-wavelength grating (HCG) is experimentally demonstrated for the first time. The waveguide is formed by two HCG planar structures and shows both transverse and lateral light confinement.
