Slit waveguide structure is proposed for mode-maintaining waveguide as regular multi-mode waveguide has an issue of mode crosstalk on waveguide that prevents proper preservation of individual mode transmission. One main cause of its crosstalk has been a mode excitation phenomenon at bending waveguide. As a result, significant mode-maintaining characteristics of almost 100% fundamental mode existence in slit waveguide while only a few % in regular multi-mode waveguide has been confirmed at 50μm radius Si/SiO2 waveguide.
