It is current thinking that the optical coupling between two parallel optical waveguides A and B is such that power is transferred equally from waveguide A to B or from B to A so long as the waveguides are loss free. Analysis of this subject, however, indicates that this is not the case. In fact, the relative power transfer can differ greatly depending on the ratio of the coupling coefficients squared.
