Abstract
For any optically interconnected assembly, the packaging tasks include alignment of one or multiple optical devices, and attachment of aligned modules to a common substrate. The concept disclosed here is a packaging method to assemble pre-aligned optical modules on a common structure called motherboard. The apparatus consists of two components: device carrier or motherboard with openings on the sides and adjustable plugs in the form of pins or balls. The method and apparatus utilize plugs as connection bridges between device carriers and motherboard, allowing solid contacts and a rigid aligned structure among modules. The direct benefits include relaxation of dimensional tolerances on parts and elimination of the need for high-precision spacers.
