Abstract
We report the operation of two‐dimensional distributed‐feedback (DFB) lasers in which periodic thickness variations exist in two orthogonal directions in the plane of the film. By using photoresist and chemical etching, two‐dimensional gratings with periods of 0.635 and 4.34 μm are formed on fused silica substrates. For the gain medium, a polyurethane film doped with rhodamine 6G is used. Emission characteristics and potential applications of two‐dimensional DFB lasers are discussed.Keywords
