Abstract

Arrays (100) of non-rod shaped optical elements (104) may be integrated with fiber arrays (108) arranged in a positioning structure (110, 114). The use of non-rod shaped optical elements allow the elements to be lithographically created already accurately aligned relative to one another. This also allows for simultaneous alignment of the array of optical elements with the array of fibers. The arrays may be one or two dimensional. The support structure for the fibers may be any desired structure. The fiber endfaces may be angled. The array of optical elements may include more than one substrate bonded together. Passive alignment features, including visual alignment mark and/or mechanical mating features, may be provided on the arrays.
