Abstract: PURPOSE:To provide an optical stationary attenuator with which a desired attenuation quantity is easily obtd. by forming core expanding parts periodically expanded in the substantial core diameter of an optical fiber by thermal diffusion and obtaining attenuation by the amplitude and period thereof and which is small in size, is high in strength and is formed by using the optical fiber. CONSTITUTION:The optical fiber 1 consists of a core 2 and clad 3 added with a dopant material and is heated at every prescribed spacing. The core expanding parts 2' where the dopant material is thermally diffused and the core 2 is expanded are formed longitudinally at the uniform amplitude and period. The mode field diameter of light expands in the expanded regions of the core 2 and, therefore, loss is eventually generated if the expanding angle of the tapered parts thereof is large. The magnitude of the loss is determined by the amplitude and period of the core expanding parts 2'. Although the loss at one point of the core expanding parts 2' is small, the attenuation quantity over the entire part is increased by increasing the number of the core expanding parts 2'. The core expanding parts 2' of the amplitude and period to obtain the desired attenuation quantity are easily formed by regulating the amplitude and period described above.
