Abstract
Optical mode converters are essential for enhancing the capacity of optical communication systems.However,fabrica-tion errors restrict the further improvement of conventional mode converters.To address this challenge,we have designed an on-chip TE0-TE1 mode converter based on topologically protected waveguide arrays.The simulation results demonstrate that the converter exhibits a mode coupling efficiency of 93.5％near 1550 nm and can tolerate a relative fabrication error of 30％.Our design approach can be extended to enhance the robustness for other integrated photonic devices,beneficial for future development of optical network systems.
