This paper investigates different factors that effect the channel density of signals propagated through fiber imaging guides. These include uniformity of the optical power transmitted through the guide, the geometrical structure of the guide, and optical crosstalk to adjacent signal channels. Two different coupling modes are also described that effect the channel density. A commercially available fiber image guide is evaluated in the context of these density considerations and experimentally tested. The resultant signal channel was found to have a diameter of 35 (m and compares favorably with electrical package densities that are projected for tape automated bonding and flip-chip bonding techniques.
