Abstract Ultra-compact mode-order converters with dielectric slots are demonstrated on a silicon-on-insulator platform. We propose a mode converter that converts the TE0 mode into the TE1 mode with an ultra-small footprint of only ${0.8} \times {1.2}\;{{\unicode{x00B5}}}{{\rm{m}}^2}$. The measured insertion loss is less than 1.2 dB from 1520 nm to 1570 nm.
