Abstract:
A temperature-insensitive polymeric optical AWG device and a manufacturing method thereof are provided to adjust the temperature characteristic of an optical element by varying the width of a trench, the distance between adjacent trenches, and the thermal expansion coefficient of an in-filled material. An input optical waveguide(200) is formed on a substrate(100). An output optical waveguide is formed to correspond to the input optical waveguide. Polymeric optical AWGs(500) with different lengths are arranged on the substrate between the input and output optical waveguides, so that free slab regions are applied at both ends of the optical waveguides. Plural hollow trenches(150) are selectively formed under the polymeric optical AWG(Arrayed Waveguide Grating) and enable the polymeric optical AWG to freely expand according to the temperature variation, so that a refraction ratio of the polymer optical AWG is destructively compensated for. A shielding layer blocks inlet holes of the hollow trenches, so that the polymeric optical AWGs are not introduced into the hollow trenches. The shielding layer supports the polymeric optical AWGs to be apart from the substrate surface.
