摘要： PROBLEM TO BE SOLVED: To provide a variable optical attenuator capable of being miniaturized without necessitating a complex mechanism such as optical axis alignment and to provide a variable optical attenuation method. SOLUTION: An optical fiber 1 is inserted into a ferrule 2 and arranged in a casing 3. The ferrule 2 is fixed by an adhesive material 4 in the casing 3. The casing 3 is provided with a temperature adding means 5 which is connected with a temperature adjusting means 6 and adds temperature to the optical fiber 1 by heating/cooling the casing 3. The optical fiber 1, whose core is added with transition metal elements such as cobalt (Co), nickel (Ni), vanadium (V), is called an optical signal attenuation fiber. The optical signal attenuation amount of the optical fiber whose core is added with a transition metal is correlated with the temperature and is reproducible. Thus, once the correlation between the attenuation amount and the temperature is established, the attenuation amount of the optical signal can be adjusted by adding the prescribed temperature.

SOLUTION: When an optical fiber 1 having a large core diameter and a high Δ optical fiber 2 having a small core diameter are welded, vicinity of a connecting section 3 is heated, the core diameter of a core 2a is enlarged to form a spot size converting section 4 so as to match the spot size of the fiber 1 with the spot size of the high Δ fiber 2, and relative refractive index differences are practically made same. Then, a cut is made for the fiber 1 at an arbitrary position so that the sections 3 and 4 are to be located inside a ferrule 5 and the fiber 1 is arranged to the optical tip surface of the ferrule 5 to realize the optical fiber parts. It is suggested to monitor the connecting loss of the section 3 while enlarging the core diameter of the core 2a. COPYRIGHT: (C)2004,JPO&NCIPI
