We demonstrate a projection lithography method that induces optical index changes in a flexible polymer cable that is
continuously translated through the image plane. We demonstrate that a static spot pattern generates a grid of
waveguides along the cable length via a continuous extrusion process. Rotations or scaling of the optical spot array can
fabricate image inverters or magnifying face plates in a single process step. The resulting polymer devices have
applications in optical backplanes, endoscopes for medical applications and lightweight imaging systems.
