Problems solved by technology

However, since the conventional preparation method of optical fiber panels includes four high-temperature steps of three wire drawing and one hot pressing, and infrared glass (chalcogenide glass, halide glass, calcium aluminate glass, germanate glass, tellurate glass, etc.) It has the characteristics of low viscosity, poor anti-devitrification performance, poor stability, etc., and has strict requirements on the molding atmosphere environment. Therefore, it is impossible to prepare optical fiber panels with an effective spectral response above 2500nm by using existing technologies

Abstract

The invention relates to an optical fiber panel and a preparation method thereof. The optical fiber panel comprises multiple optical fibers which are arranged in arrays. The optical fibers are formed by channel glass and core material glass. Core material glass of the optical fiber panel is infrared glass. The preparation method of the optical fiber panel comprises the following steps that a glass rod tube complex is manufactured by channel glass and acid soluble glass, and an acid soluble blank is manufactured by the steps of wire drawing, typesetting and thermal pressing; acid soluble glass in the acid soluble blank is corroded by acid solution so that micropore arrays are manufactured; and molten infrared glass fills the micropore arrays under the effect of pressure, and the optical fiber panel is manufactured by cooling and optical polishing. The invention provides the novel preparation method of the optical fiber panel. According to the method, infrared glass can be adopted to act as core material glass so that effective spectrum response of the optical fiber panel is enabled to be more than 2500nm. A new idea is provided for preparation of the optical fiber panel so that the preparation method of the optical fiber panel can be applied to preparation of multiple optical fiber panels.
