چکیده
A silicon-on-insulator grating coupler with a broad 1-dB bandwidth of 76nm and a coupling efficiency similar to that of a standard grating coupler is experimentally demonstrated. The design is based on a novel two-way-fed method. OCIS codes: (050.0050) Diffraction and gratings; (130.0130) Integrated optics

High-efficiency Silicon-On-Insulator Fiber-to-Chip Grating Couplers Using a Silicon Overlay
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.

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 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.
