Silicon Waveguide Grating Couplers with Engineered Coupling Strength for Optimized Coupling
نویسندگان
چکیده
We describe simulation and experimental results of gratings for coupling between optical fibers and nanophotonic waveguides. The coupling strength was engineered to obtained Gaussian-like output profile. 1.2dB coupling loss is achieved to single-mode fibers. Preliminary experimental result for coupling with vertical fiber with chirped grating gives a 3dB coupling loss.

We present a single-lithography Mach-Zehnder interferometer sensor circuit, with integrated low back-reflection input and output grating couplers. The low back-reflection is accomplished by a duty cycle apodization optimized for coupling light between single-mode silica fibers and the nanometric silicon-on-insulator (SOI) rib-waveguides. We discuss the design, fabrication, and characterization ...
