We describe new planar multiport devices written by spatial solitons that are composed of several nonlinearly
coupled components in Kerr-type media. Such devices have no radiation losses at a given wavelength. We
demonstrate that, for the same relative angle between the input soliton-induced channels, one can vary the
transmission coefficients into the output channels by adjusting the polarizations of multicomponent solitons.
We determine analytically the transmission properties and discuss two types of experimental embodiment of
the proposed device. 2003 Optical Society of America

It has been suggested that two colliding spatial soli-
tons that are formed in a nonlinear Kerr-type medium
induce a change of refractive index, and this can be
viewed as a linear X junction or coupler.1
