Abstract

Linear arrays of optical fibers are aligned to linear arrays of optoelectronic devices (e.g., photodiodes, diode lasers or LEDs) formed on an elongated chip. The alignment procedure results in a subassembly which includes fiber segments embedded between V-groove mounting blocks and the device array chip affixed to an end face of the blocks.
