An optical cross connect device for switching light signals including a plurality of first optical fiber light guides positioned substantially parallel to each other. Each of the first optical fiber light guides includes a core and cladding, and each of the first optical fiber light guides has formed therein a plurality of linearly spaced apart notches through the cladding to expose the core. A plurality of substantially parallel second optical fiber light guides having cores and cladding, and being notched in similar fashion to the first optical fiber guides, are engaged with the first optical fiber guides to form a plurality of junctions. Each of said junctions normally forms a discontinuity of refractive indices and absorption with the cores of the first and second optical fiber light guides. The discontinuity of refractive indices is removable at a selected junction, thereby to permit light signals to pass from one of the first optical fiber light guides to one of the second optical fiber light guides across the selected junction. |
