Simulated addition of PM fiber modes. (a) and (b) When the two excited fiber modes are coherent with respect to each other, i.e. their phases are correlated, the resulting mode depends on their relative phase. This means that fiber bending will change the output by changing the relative phase. (c) If the two modes share no phase correlation, the resulting mode is a doughnut shape regardless of relative phase19,20,21.
