Abstract
PURPOSE:To easily manufacture an optical fiber having a desired elliptical core part by depositing a glass film for the core of the fiber on the inner wall of a hollow glass pipe, making the section of the pipe elliptical, grinding the outside to a perfectly round shape, and heating and drawing the pipe. CONSTITUTION:On the inner wall of a perfectly round hollow glass pipe a glass film for a core part having a higher refractive index than the glass pipe is deposited by a vapor phase chemical reaction, and after evacuating the glass pipe, the pipe is melted by heating and bonded to the glass film so as to make the cross-section of the pipe elliptical. Thus, a base material 3 composed of a solid rodlike core part 1 having the desired elliptical shape and a clad layer 2 is obtd. The outside of the material 3 is then polished to a perfectly round shape. By attaching the resulting base material 3' to a spinning device and spinning it at a prescribed drawing rate, and optical fiber composed of a perfectly round clad layer 22 and an elliptical core part 21 can be obtd. easily. This fiber can transmit a photo signal having a prescribed polarizing face without rotating the polarizing direction.
