Abstract:
PCT No. PCT/GB91/01073 Sec. 371 Date Feb. 18, 1993 Sec. 102(e) Date Feb. 18, 1993 PCT Filed Jul. 2, 1991 PCT Pub. No. WO92/00538 PCT Pub. Date Jan. 9, 1992.An optical system comprises a hybrid optical motherboard having a plurality of optical interconnections formed therein, and a connector. A connector region is formed in, but does not extend completely along, an edge portion of the hybrid optical motherboard. The connector region contains a number of optical interconnections, and the connector contains an optical device. The connector is connectible to the connector region to align the optical device of the connector with the optical interconnections contained in the connector region. The connector and the connector region each comprises first and second substrates made of crystalline material and containing intersecting planes which can be delineated by etching. Each first substrate is formed with etched alignment grooves, and each second substrate is formed with etched alignment grooves which are complementary to the alignment grooves of the associated first substrate. The alignment grooves of the first and second substrates of the connector and of the connector region are accurately aligned and contiguous when the two substrates are placed in face-to-face engagement, and the aligned contiguous alignment grooves of the connector can be accurately provided with an alignment mechanism for accurately positioning the associated optical device between its two substrates with respect to the contiguous aligned grooves thereof.
