Title: Polarized wave storage fiber and method for manufacturing the same
Inventor: YAMAMOTO TETSUYA
IPC: C03B37/012
Filed: 2001-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a polarized wave storage fiber which can be easily manufactured and has desired optical propagation characteristics, and a method for manufacturing the same. SOLUTION: A preform of the polarized wave storage fiber is constituted by arranging a core member 1 being a rod in its center, and by forming and arranging 1st cladding members 23 being capillaries on both sides of the member 1, up to an inner wall of a support pipe 19 in a sectorial shape. The 2nd cladding members 25 being the rods are filled between two sectors formed with the 1st cladding members 23, and two sectors are formed with the 2nd cladding members. The cladding is divided into four by the boundaries extended in the radial direction from the core after drawing processing of the preform. Since the effective refractive index of the cladding part originated in the 1st cladding members 23 becomes lower than that originated in the 2nd cladding members 25, the birefringence is produced, and the polarized wave storage fiber is obtained.
