Abstract
We have reduced the propagation loss of an antiresonant reflecting optical waveguide (ARROW) to 0.3 dB/cm in a short wavelength band by employing a transparent TiO_2/SiO_2 interference cladding. We developed a new analysis method for ARROW in order to analyze its propagation characteristics. In addition, we stacked two uncoupled parallel ARROW's with only 2-μm spacing, aiming at three-dimensional optical interconnectionKeywords
