PURPOSE:To fix an optical fiber with a high precision, by fitting an insulating optical fiber holding material to the end part of the fixing side of an optical fiber and heating a melt-stuck material, which is provided in the fixing end, with an induced current to melt and solidify this melt-stuck material and fixing the optical fiber holding material to a fixed material. CONSTITUTION:An optical fiber holding material 3 consisting of glass, ceramic, or the like to which an optical fiber 1 is inserted is fitted to a conical aperture part provided on a rod lens 2. A current is flowed to a coil 5 by an electric pulse generator 5 to melt and solidify the melt-stuck material such as a glass solder or a vacuum-deposited metal, which is provided on the side end face of the holding material 3, with the Joule heat due to the induced current, thereby connecting the optical fiber holding material 3 and the rod lens 2. Thus, the optical fiber is fixed with a high precision. |
