Single-leakage-channel grating couplers: comparison of theoretical and experimental branching ratios

Fabrication and characterization of a waveguide grating that is highly efficient in producing a single channel of output-coupled light are described. The thin-film assembly consisted of a waveguide-grating system fabricated upon a highly reflecting dielectric stack and isolated by a thick buffer lay...
