Mode-Insensitive Waveguide Crossing on Lithium Niobate-on-Insulator Platform
We experimentally demonstrate a mode-insensitive waveguide crossing on lithium niobate-on-insulator using a multimode interference structure, achieving <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$<0.22 \text{dB}$</tex> insertion loss and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$<-25 \text{dB}$</tex> crosstalk over 40 nm for <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$T E_{0}$</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$T E_{1}$</tex> modes.
