摘要

提出了一种在250 nm绝缘体上硅平台上使用具有增强光带宽的硅光栅耦合器的高效光纤到芯片链路的设计。该链路由带后视镜的标准光栅耦合器和特殊的色散涂层组成，设计简单，带宽提高1db。特别注意了涂层色散对带宽的影响。光学仿真证明了光纤到芯片链路在约1550 nm波长和横向电波导模式下的性能。

Bandwidth-Enhancement of Silicon Grating Couplers Using Dispersive Coatings

The design of a highly efficient fiber-to-chip link using a silicon grating coupler with an enhanced optical bandwidth in a 250 nm silicon-on-insulator platform is presented. Consisting of a standard grating coupler with backside mirror and a special dispersive coating, this link offers a simple design and an enhanced 1-dB-bandwidth. Special attention is paid to the influence of the coating-dispersion on bandwidth. Optical simulations demonstrate the performance of the fiber-to-chip links at a wavelength of about 1550 nm and for the transverse electric waveguide mode.
