OPTICAL WAVEGUIDE LATERAL ALIGNMENT ARRANGEMENT Abstract An arrangement for providing optical coupling between a pair of substrates is disclosed. The arrangement is capable of providing automatic alignment in the lateral direction, that is, the direction perpendicular to the direction of optical signal flow along the surface of the optical substrate. In accordance with the teachings of the present invention, an interlocking system of alignment grooves and alignment ridges are utilized to prevent this unwanted motion and aid in alignment between the two pieces. In particular, an alignment ridge, or ridges, are formed on the top surface of a first substrate and are disposed to be parallel with a plurality of optical waveguides formed in the first substrate. The corresponding alignment grooves are formed in the second substrate, where this substrate may contain a plurality of fibers held in associated v-grooves. Waveguide-to- waveguide communication is achieved by forming alignment ridges on a pair of waveguide containing substrates. The substrates may then be placed end-to-end, where the alignment grooves in the second substrate will interlock with both sets of alignment ridges. As long as the dimensions of the alignment ridges and grooves are formed to complement each other in size - and are spaced similarly in their respective substrates - the alignment ridges and grooves will interlock when the two substrates are joined, thus preventing motion between the two substrates in the lateral direction.
