Abstract: PURPOSE: A polyimide for an optical communication and its production method are provided to minimize an optical traveling loss in an area of near infrared rays and to compensate a weak point to depend a wave characteristic of light on a polarized light by reducing a birefrigence. CONSTITUTION: A first polyimide film is produced by coating and thermally processing on a substrate after melting a polyimide or a polyamic acid in an organic solvent. The polyamic acid passes through a thermal process within 250-350°C when the polyimide film is formed by using the polyamic acid as a polyimide precursor. A second polyimide film is completed by coating and thermally processing on the substrate after melting the polyimide or the polyamic acid in the organic solvent on the first polyimide film. A multi-layered polyimide film is completed by forming more than one polyimide films on the second polyimide film as occasion commands by using the polyimide or the polyamic acid.

Abstract: PURPOSE: An optical waveguide is provided to increase a refractive index difference between a core and a clad by using a polyimide for controlling the refraction index. CONSTITUTION: An optical waveguide comprises a core and a clad. The core is formed with a polymer. The core is adjacent to the clad. The clad is formed with a polymer less than a refraction index of the polymer for forming the core. A polyimide is used for controlling the refraction index. The difference range of the refraction index between the core and the clad of an optical waveguide element is controlled within 0.25% to 2.0% when the polyimide is used for controlling the refraction index.

Abstract: PURPOSE: A process for controlling the thickness of polyimide film without changing the content of polyimide precursor is provided which makes it possible to control the thickness of thin film of core layer without difficulty and form multi-layer film. CONSTITUTION: The process comprises a)the heat treatment process of polyimide precursor composition comprising polyamic acid and solvent at 50-100°C for 5-13 hr, b)the amidation process of the polyimide precursor composition after coating it on a base plate and drying at 50-400°C. For an example 17.2g polyamic acid is added with 57.35g N,N-dimethylacetate and heat-treated. The heat-treated polyamic acid composition is spin-coated on a silicone substrate, and the silicone base plate is heated to 350°C by stages to form a polyimide film. As time goes by, the viscosity of polyamic acid composition decreases gradually, i.e., the viscosity is 400,000 cps after 1 hr, but it falls to 13,000 cps after 11 hr.
