摘要： Disclosed are an optical fiber preform manufacturing apparatus and method in which processes for shrinking and closing a deposited tube are conducted using a device suitable for those processes, which device is other than the device used in a deposition process for forming the deposited tube on the inner surface of a preform tube, thereby reducing the processing time while reducing the amount of OH penetrated from the preform tube into a vitreous component of the deposited tube, thereby achieving a reduction in OH loss. In accordance with the optical fiber preform manufacturing apparatus and method, operations are conducted which involve setting the heating temperature of a circular heater to a temperature lower than the softening point of a deposited tube, exhausting contaminants existing in the interior of the deposited tube while moving the circular heater at a desired temperature, setting the heating temperature of the circular heater to a temperature not lower than the softening point of the deposited tube, and shrinking and closing the deposited tube while moving the circular heater to a desired temperature.

摘要： A photonic crystal fiber (PCF) preform, from which a photonic crystal fiber is manufactured, includes a rod-shaped substrate with holes longitudinally formed therethrough in a photonic lattice structure, and material layers having at least two different indices of refraction. The material layers are disposed in the holes, respectively. Distribution of index of refraction of the photonic crystal fiber preform is controlled by arrangement of the material layers. Consequently, an optical fiber with very low optical loss, very low optical nonlinearity and excellent transmission characteristics can be easily manufactured, and an optical fiber with various characteristics, differing depending upon the lattice structure, can be realized.
