Abstract
An article is disclosed having a non-planar surface with a high-resolution pattern formed thereon, particularly a distributed-feedback (DFB) ridge waveguide laser. An elastomeric member having relief patterns on its surface is used to print or mold a pattern directly onto the non-planar surface of the waveguide. A range of materials disposed on such non-planar surfaces can thus be patterned at high resolution to provide devices with sub-micron features at low cost with potential applications in optoelectronics. For example, a plastic laser based on molded organic gain materials may be made.
