ABSTRACT:
An optical fiber type polarizer comprises a first optical fiber constituted by a birefringent optical fiber wound at a predetermined winding radius and having winding start and end fixed to each other by an adhesive, the first optical fiber having short extra portions respectively extending from the winding start and end, and the length of each of the short extra porions being at least as small as the predetermined winding radius. The optical fiber type polarizer further comprises a second optical fiber spliced to one of the short extra portions of the first optical fiber, and a third optical fiber spliced to the other of the short extra portions of the first optical fiber.
