Extrusion of polymer waveguides onto surfaces |
摘要 |
A waveguide structure is directly extruded onto a surface from a nozzle placed a predetermined distance above the surface and which is moved relative to the surface, preferably by means of a translation table. The predetermined distance is preferably maintained constant and the speed of relative motion regulated to achieve a uniform degree of molecular orientation within the extruded material, thus maintaining a sufficiently uniform refractive index along the axis of the waveguide. Partitions within the nozzle allow the formation of a layered waveguide or the simultaneous formation of concentric cladding or protective layers. The waveguides are advantageously formed as a curtain which is later patterned, by direct writing on the surface or between chips mounted on an electronic module.
