Abstract
An enhanced self-writing method for generating in-plane (horizontally-oriented) polymer lightguides that includes disposing one or more light deflecting structures in or on the upper surface of a uncured layer that deflect incident collimated light beams in a transverse direction (i.e., parallel to the uncured layer top layer surface), whereby the deflected collimated light beam polymerizes a corresponding elongated portion of the uncured material in a self-propagating manner to form in-plane polymer lightguides. When used in the fabrication of micro-truss structures, the in-plane polymer lightguides are linked to diagonal polymer lightguides to form superior truss configurations, such as that of the ideal octet-truss structure. Non-polymerized portions of the uncured layer are removed to expose the micro-truss structure for further processing.
