Abstract

The present invention is a continuous process of producing an object with radially-varying material properties. These objects can be cylindrical forms made from polymeric materials. This process requires a novel device. The device can be used to produce high bandwidth gradient-index plastic optical fiber (GRIN-POF). This fiber is highly advantageous for use in high speed local area networks (LANs) as well as other short-range optical communication applications. The device can also be used to produce GRIN lenses which can be used in the focusing and transmission of images.
