The waveguiding characteristics of a novel power switch with one input andnoutputs (1×n) using oblique incidence to a nonlinear slab is proposed. With a proper incident optical power, the emitted soliton in the nonlinear slab can be efficiently directed to any waveguide in a array ofnwaveguides. For digital signal switching application, the numberncan be increased simply by increasing the slab thickness. Moreover, it is found that the soliton offsets calculated by Snell’s law with an index obtained by averaging over the index distribution are in good agreement with those calculated by the beam propagation method. ©1995 American Institute of Physics.
