Mode splitters that directly separate modes without changing their orders are highly promising to improve the flexibility of the mode-division multiplexing systems.In this paper,we design a high-performance mode splitter on the silicon-on-insulator platform with a compact footprint of 14 μm× 2.5 μm using an inverse design method based on shape optimization.The fabrication of this mode splitter requires only a single lithography step and exhibits good fabrication tolerances.The experimental results show that the proposed device exhibits state-of-the-art insertion loss[＜0.9 dB]and cross talk[＜-16 dB]over a broad bandwidth[1500-1600 nm].Furthermore,the shape optimization method used is implemented to design a dual-mode[de]multiplexer,and the experimental results fulfill the design objective,demonstrating the excellent generality of the design method in this paper.
