Transfer of light energy from one fiber to another due to a direct coupling mechanism can be used in various applications in all-optical data communication. We report an analytical approach for finding the exact amount of coupled light from one waveguide to other, if the nonlinearity of the guiding media is considered in this coupling. The significant difference of this coupling phenomenon (effected by the nonlinearity of the waveguide) with the conventional coupling mechanism obtained as coupled optical output is also discussed.
