Grating 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 کاملSilicon Waveguide Grating Couplers with Engineered Coupling Strength for Optimized Coupling
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.

متن کاملFiber to Waveguide Couplers for Silicon Photonics
As silicon photonics enters mainstream technology, we find ourselves in need of methods to seamlessly transfer light between the optical fibers of global scale telecommunications networks and the on-chip waveguides used for signal routing and processing in local computing networks. Connecting these components directly results in high loss from their unequal sizes. Therefore, we employ a coupler...
