  We introduce a new type of Fano resonances, realized in a photonic circuit
which consists of two nonlinear PT-symmetric micro-resonators side-coupled to a
waveguide, which have line-shape and resonance position that depends on the
direction of the incident light. We utilize these features in order to induce
asymmetric transport up to 47 dBs in the optical C-window. Our set-up requires
low input power and does not compromise the power and frequency characteristics
of the output signal.
