Abstract : Recently nonlinear waveguide junctions have been investigated intensively for their interesting switching behaviors. The waves propagating in a nonlinear converging waveguide Y junction in which the two branches and the stem are single mode waveguides are less reported. For a linear case, the field injected into the thinner branch at a distance from the junction will not evolve into the fundamental mode of the stem, and the field injected into the thicker branch will propagate without loss. Here we simulate the waves propagating in the Y junction with a nonlinear cladding by using beam propagation method, and we find that the field injected into the thinner branch is possible to transmit to the stem with a high efficiency.
