Abstract

Good alignment of the light beams and devices is necessary for maximum efficiency and reliability of an optical interconnection system. An optical interconnect which is difficult to align will be costly to manufacture and deploy. A measure of the ease with which a single beam of light and a device a basic optical interconnect can be aligned has been developed. This measure the alignability is a function of the beam size the spot size and the overall cost measure associated with the alignment. Practical optical interconnects consisting of several optical beams and devices such as optical crossbar switches can be modeled as series and parallel combinations of basic optical interconnects. The overall alignability can be obtained from the alignabilities of the component interconnects. A set of formulas for calculating component interconnects involving Gaussian and/or uniform beams and devices are derived. Using these formutas the alignability of several optical interconnection schemes and design and packaging guidelines can be developed.
