Abstract
A silica material having a higher purity than a cylindrical preform formed of a silica material is deposited on at least one of an inner side and an outer side of the preform to fabricate a cylindrical intermediate member. A part of the cylindrical intermediate member including at least a part of the preform is removed to fabricate a high-purity silica tube. A plurality of the high-purity silica tubes is bundled with a core rod arranged at a center axis of a bundle of the high-purity silica tubes, and the bundle of the high-purity silica tubes with the core rod arranged at the center axis is drawn to obtain a microstructured optical fiber.
Claims5
A method of manufacturing a microstructured optical fiber, the method comprising:
- depositing a first silica material having a higher purity than a cylindrical preform formed of a second silica material on at least one of an inner side and an outer side of the preform to fabricate a cylindrical intermediate member;
- removing a part of the cylindrical intermediate member including at least a part of the preform to fabricate a high-purity silica tube;
- bundling a plurality of the high-purity silica tubes with a core rod arranged at a center axis of a bundle of the high-purity silica tubes;
- and
- drawing a bundle of the high-purity silica tubes with the core rod arranged at the center axis.
