Abstract

Mode-division multiplexing (MDM) is an effective solution to improve the integration of photonic integrated circuits. MDM systems increase the number of channels for data transmission by introducing higher-order modes. The mode converter is a key component for MDM. In this work, we propose a novel ultra-compact mode converters in the silicon-on-insulator platform, combining beam splitters with nano strips. The nano strips are used to achieve the phase matching. The high-performance TE₁-TE₀, TE₂-TE₀, and TE₃-TE₀ mode converters exhibit high conversion efficiency and broad transmission bandwidth, in ultra-small footprints.
