摘要

The use of grating couplers in high index contrast waveguides like silicon on insulator (SOI) offers several advantages over other coupling approaches, including better alignment tolerances and allowing for wafer-scale testing. The grating couplers were developed for nanometric SOI waveguides (Si-wires), and recently also for micrometric rib waveguides. In this paper we review our work in fiber-to-chip grating couplers for thick SOI rib waveguides, where a coupling efficiency of - 2.2 dB was demonstrated experimentally. We also discuss the use of grating couplers to improve optical throughput (etendue) of a planar waveguide Fourier-Transform (FT) spectrometer implemented in thick rib waveguides.
