Theoretical and experimental performances of a robust Si-based spot-size converter (SSC) for efficient coupling between a single-mode fiber and a photonic Si-wire waveguide are reported. The SSC is comprised of cascaded horizontal linear and vertical nonlinear up tapers measured 2.0 mm and 86 mu m in length, respectively, in a silicon-on-insulator substrate. The fine modal field of a Si-wire waveguide, 0.54x0.38 mu m(2) in diameters, was expanded to diameters of 5.1x9.2 mu m(2) with measured net transmission loss of 0.5 dB at the wavelength of 1.55 mu m by the miniature SSC.
