Title: Method of manufacturing optical fiber with elliptic core, and worked preform used for manufacturing the same
Inventor: OKAGAWA SHUJI
IPC: C03B37/027
Filed: 2002-03-19
Abstract: PROBLEM TO BE SOLVED: To surely manufacture an optical fiber with an elliptic core having a desired dimension by employing a method where the optical fiber is manufactured by heating and drawing the preform, which has a circular core arranged in the center of a circular clad, after working and flattening it. SOLUTION: The aspect ratio of the worked preform is calculated in order to obtain a desired aspect ratio of the elliptic core based on the correspondence relation between the aspect ratio of the preform, which is worked and flattened, and the aspect ratio of the elliptic core in the optical fiber with the elliptic core The ratio of the core radius/the outer radius of an original preform is calculated in order to obtain a desired ratio of the core cross-sectional area based on the correspondence relation between the aspect ratio and the ratio of the core cross-sectional area of the worked preform. The worked preform having the above aspect ratio is composed by working the above original preform.
