摘要
A grating-based approach to exciting higher order fiber modes in a few mode fibers is presented. By exploitation of higher order modes of silicon on insulator nanowaveguides and by the illumination of the grating from opposing ends, the LP01, LP11,a, LP11,b, and LP21,a fiber modes could be excited in two orthogonal polarizations. Simulative and experimental results as a proof of principle are presented.
