Optical Devices Grating Couplers
In this paper, we review the current research progresses made on grating couplers, starting from their fundamental theories and concepts. Surface grating coupler is a preferred candidate that provides flexibility for circuit design and reduces effort for both fabrication and alignment. The built-in particle swarm optimization tool is used to maximize the coupling efficiency, and a compact model in INTERCONNECT is created using the component S-parameters. ce between its high-performance integrated waveguide devices and optical fibers or free-space optics.
