ABSTRACT:
In order to make alignable optical waveguides, an alignment structure is formed on at least one opposable end of the waveguides by selective chemical etching of different portions of the waveguides. The waveguides can then be brought into alignment with the alignment structure. Preferably, a pair of complementary alignment structures are formed on opposed ends of adjoining waveguides.
