Active waveguiding properties of micro-rods made of chiral organic compound R-Binol by the self-assembling method, in two-and three-photon nonlinear-optical response are studied using a multiphoton microscopy method. The dependences of two- and three-photon luminescence intensity on the distance between the excitation and collection points under two circular fundamental beam polarizations were obtained. Constants of waveguiding losses for the two-photon and three-photon luminescence are measured. We demonstrated the nonlinear optical circular dichroism effect in waveguiding regime.
