Each coupler has a characteristic portrait, revealing its unique physics. We believe that this approach is novel to all branches of nonlinear theory. Full details are given for nonlinear couplers with...
Here, we validate these predictions in an optics context using a mode-locked fibre laser. We confirm that the coupling is universal and approximately satisfies a general scaling law.
