| titleOfInvention | Design of low insertion loss, single-mode polymeric waveguides |
| abstract | The invention provides organic optical waveguide devices which are lithographically formed and employ polymeric materials having low propagation loss. An optical waveguide has a substrate (2); a polymeric buffer layer (4) on a surface of the substrate; a thin, polymeric undercladding layer (6) on a surface of the buffer layer; a pattern of a light-transmissive, polymeric core (8) on the surface of the undercladding layer; and a polymeric overcladding layer (10) on a top surface of the core and on sidewalls of the core and on a portion of the undercladding layer; the undercladding layer having a thickness of from about 10 percent to about 50 percent a thickness of the core. The core has an index of refraction nc which is greater than an index of refraction of the overcladding layer no and also greater than an index of refraction of the undercladding layer nu; wherein Δn = nc - no , and wherein the difference between nc and the index of refraction of the buffer nb is at least about 1.5 times Δn. |
