چکیده
We present the realization of a new generation of Silicon-On-Insulator fiber-tochip grating couplers which use a silicon overlay to enhance the directionality and thereby the coupling efficiency. Devices fabricated in a CMOS pilot line show a coupling efficiency of -1.6dB and a 3dB bandwidth of 80nm.

High-efficiency fiber-to-chip grating couplers realized using an advanced CMOS-compatible silicon-on-insulator platform.
A new generation of Silicon-on-Insulator fiber-to-chip grating couplers which use a silicon overlay to enhance the directionality and thereby the coupling efficiency is presented. Devices are realized on a 200 mm wafer in a CMOS pilot line. The fabricated fiber couplers show a coupling efficiency of -1.6 dB and a 3 dB bandwidth of 80 nm.

We present the design, fabrication and characterization of efficient fiber-to-chip grating couplers on a Germanium-on-Silicon (Ge-on-Si) and Germanium-on-silicon-on-insulator (Ge-on-SOI) platform in the 5 µm wavelength range. The best grating couplers on Ge-on-Si and Ge-on-SOI have simulated coupling efficiencies of -4 dB (40%) with a 3 dB bandwidth of 180 nm and -1.5 dB (70%) with a 3 dB bandw...
متن کاملReflectionles grating couplers for Silicon-on-Insulator photonic integrated circuits
We propose a novel grating coupler design which is inherently reflectionles by focusing the reflecte light away from the entrance waveguide. The design rules for this reflectionles grating coupler are explained and the grating coupler design is investigated by means of 3D FDTD simulations for the case of a Silicon-on-Insulator based platform.

متن کاملGrating Couplers for Coupling between Optical Fibers and Nanophotonic Waveguides
Nanophotonic waveguides and components are promising for use in the large-scale integration of photonic circuits. Coupling light between nanophotonic waveguides and a single-mode fiber is an important problem and many different solutions have been proposed and demonstrated in recent years. In this paper, we discuss a grating coupler approach. Grating couplers can be placed anywhere on a circuit...
متن کاملUltrahigh-efficiency apodized grating coupler using fully etched photonic crystals.
We present an efficient method to design apodized grating couplers with Gaussian output profiles for efficient coupling between standard single mode fibers and silicon chips. An apodized grating coupler using fully etched photonic crystal holes on the silicon-on-insulator platform is designed, and fabricated in a single step of lithography and etching. An ultralow coupling loss of -1.74 dB (67%...
