“…RSS analysis is fast, but it is known that this method is not valid as error functions for optical systems are not additive and tolerances are not linearly independent. Finally, it is possible to obtain an accurate determination of misalignment tolerance by performing a Monte Carlo analysis [44], [14]. Many simulated systems are generated in which all components are assumed to be misaligned with some suitable probability distribution and the final throughput in each case is calculated.…”

Recently, a number of successful free-space chip-to-chip and board-to-board optical interconnects have been demonstrated. Here, we present some of the design rules that can be derived as a result of this work and also as a result of numerical and theoretical analyzes. We draw a number of conclusions. In the area of optoelectronic very large scale integration (VLSI) design, we suggest that differential electrical and optical transceiver designs provide the best performance. In the area of optical design, we present scaling and system partitioning laws for clustered optical relays and determine the interconnect distances at which microlens or macrolens systems are more suitable. We also show that the ease with which two modules can be aligned can be related to the optical invariant of the system and is, thus, a function of the size of the detector and the numerical aperture of the detector optics. Finally, we show that when multiple optical components must be aligned, very high individual component tolerances are required if the system as a whole is to have a high chance of success.

“…1. 12 We described the system as a series of elements, specifying the thickness, index of refraction, and radius of curvature of each. We then modeled the propagation of a Gaussian beam through the system using the complex beam parameter, q, and the ABCD-matrix-transfer method.…”

“…There have been a number of studies on FSOI systems, its alignment, tolerancing, and packaging. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] In the present study, we approached the problem from a statistical point of view that was focused on the development of a probabilistic relationship between the system performance and tolerance variables in the form of a prediction equation. Such an equation could then serve as the basis for the design, evaluation, and optimization of the FSOI system.…”

System-level packaging is one of the critical issues that need to be addressed for free space optical interconnections (FSOI) to become useful in desktop systems. The performance of FSOI, e.g., in terms of system bit-error rate, is greatly affected by misalignments in the optical system. Therefore tolerancing, i.e., the ability to analyze and predict the effects of misalignments in the system, is of prime importance to system designers. We introduce an approach in which we study the effects of optical misalignments and other tolerance factors using statistical methods. We use Monte Carlo simulations, design of the experiments, and regression techniques to fit a polynomial equation that expresses the relationship between the system performance and the tolerance factors. This prediction model can be used for design, cost optimization, and quality control purposes. In addition, we perform a sensitivity analysis to determine those tolerance variables that have the greatest effect on system performance.
