Introduction
David James Welker, an accomplished inventor based in Vancouver, Washington, has made significant contributions to the field of optical devices. With a total of seven patents to his name, Welker has developed innovative methods and technologies that enhance the capabilities of polymer optical materials.
Latest Patents
Among his latest patents, one notable invention is the method for forming polymer optical devices through mold-constrained relaxation expansion. This process involves creating a polymer billet that retains residual stress and utilizing a mold that constrains the billet's transverse expansion to achieve a desired waveguiding optical component shape. By heating the billet in the mold, the residual stress is released, allowing the material to adopt the intended shape.
Another significant patent is the pellet-start process for creating transverse Anderson localization (TAL) elements. This method employs a mixture of distinct material pellets with varying wave speeds to provide guiding capabilities. The pellets are fused into a preform, which is then stretched to produce the final TAL element.
