摘要: A method for establishing optical coupling between spatially separated first and second planar waveguides includes arranging an interconnect on the waveguide. The has end portions intermediate portion. Each of inverse taper. waveguide is arranged so that overlaps with one tapered but not other portion to thereby enable adiabatic transition signal from via interconnect. have different refractive indices at operating wavelength a higher index than core
