Abstract: We numerically and experimentally investigate the power transfer characteristics between super-modes in coupled multi-core fibre. We reveal that fibre twisting and bending considerably affect mode coupling and show how to suppress impulse response spread taking account of adiabatic/nonadiabatic mode conversion.
