Abstract: Techniques for controlling the flow of replication material (e.g., epoxy) during the formation of replicated optical elements include providing a transparent substrate (220) onto which the optical elements are to be replicated.

Abstract: Fabricating light guide elements includes forming a first portion of the light guide element using a replication technique (104), and forming a second portion of the light guide element using a photolithographic technique (106). Use of replication can facilitate formation of more complex-shaped optical elements as part of the light guide element.

In some instances, at least part of the yard portion is embedded within the second portion of the light guide element, thereby resulting in a smoothing over of the yard portion.
