Abstract: An anisotropic structure formed by the photoinduced color centers in the switching zone of the 1 $MUL 8 fiber coupler was created and investigated. Using the property of an orientational ordering for the photowritten grating with the effective second harmonic generation the growth of an energy transfer for the probe cw He-Ne beam from the central fiber core to the selected 1 $MUL 8 exit fibers was detected and discussed.!4
