| Abstract | We present experimental results on a novel fiber-chip grating coupler for silicon photonic wire waveguides. By using subwavelength grating structures, which act as an averaged effective medium inside the grooves of the diffraction grating, the grating strength can be varied continuously to optimize the mode overlap of the diffracted beam with the fiber mode. Grating couplers and photonic wire waveguides are fabricated in a single etch step. We have measured maximum fiber-to-photonic wire coupling efficiencies of approximately 40% for the transverse magnetic (TM) mode. |
