FIG. 1 is a schematic diagram showing an embodiment of the optical fiber polarizer of the present invention, in which a is a front view, b is a cross-sectional view,
Figure 2 shows an example of the loss wavelength characteristics of an optical fiber polarizer when its coil diameter is at its minimum, and Figure 3 shows the loss when the operating wavelength is shifted by changing the winding tension of the optical fiber polarizer of the present invention. The diagrams illustrating examples of wavelength characteristics, FIGS. 4 and 5, are sectional views each illustrating a coil support whose outer diameter can be changed. In the figure, 1 is a coiled optical fiber polarizer, 2 is a coil support, 3 is a polarization preserving optical fiber, 4 is an outer periphery, 5 is a hollow part, 6 is an adjustment valve, and 7 is an outer periphery of the coil support. The cylinder 8 is a wedge-shaped core material.
