Abstract
Stackable waveguides provide for spaced superposition of multiple two-dimensional planar arrays while closely packing pixels in an array. Multiple ports of each waveguide accommodate a collimated beam input. The beam is reflectively split to allow control or detection by strategically placed two-dimensional arrays of control or sensing elements. These elements may be any number of different kinds of control devices or, if used to receive, detectors. One embodiment of the present invention has six port modules horizontally and vertically stacked with other six port modules. The devices can be stacked in such a way that the chip carriers can be caused not to interfere with each other. Circuits and two-dimensional arrays are spaced within the stacks while the outputs are tightly packed. Multiple port module configurations are horizontally and vertically stacked to produce a tightly packed array of programmable pixels.
