In.this work, we exploit the effective couplin. of electric an. toroidal modes in.AIGaAs n.n.dimers to locally en.an.e both electric an. magn.tic fields while min.mizin. the optical scatterin., thereby optimizin. their secon.-harmon.c gen.ration.efficien.y with respect to the case of a sin.le isolated n.n.disk.
