Mode Converters of LP<sub>51</sub> Core Mode Coupling Based on Long-Period Fiber Gratings
We demonstrate the inscription of multi-cascaded long-period fiber grating in a few-mode fiber using a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{CO}_2$</tex> laser. The mode conversion from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{LP_{01} -LP_{11}}$</tex> mode, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{LP_{11} -LP_{21}}$</tex> mode, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{LP_{21} -LP_{31}}$</tex> mode, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{LP_{31} -LP_{41}}$</tex> mode, and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{LP_{41} -LP_{51}}$</tex> mode can be achieved.
