    摘要： A temperature-compensated optical fiber component for use in high-density WDM optical communication includes an optical fiber which has a Bragg grating serving as a monochromatic filter, an inner package which supports the optical fiber and causes the Bragg grating to have a temperature-compensating capability, and an outer package arranged outside the inner package. A clearance having a heat insulating function is provided between the outer package and the inner package.

    摘要： A grating-type optical component having a high isolation ability at a light-blocking band and a small clad layer mode combination loss at a signal transmission band, and its manufacturing method are provided. A selected area on a core of an optical fiber is irradiated by ultraviolet beams emitted from an excimer laser source through a phase mask in order to produce high index of refraction areas and low index of refraction areas arranged alternately and periodically along the longitudinal axis of the optical fiber. This ultraviolet irradiation is terminated before the index of refraction, which is increasing due to the ultraviolet irradiation, reaches a target value. Then, the phase mask is removed, and the selected area of the core is again irradiated by ultraviolet beams, thereby completing the grating-type optical fiber.

    摘要： An optical fiber coupler in which portions in the lengthwise direction of a plurality of optical fibers whose surface is coated with a carbon film are welded to each other and extended to form a connected portion, and the connected portion is not coated with a carbon film. This coupler is manufactured by arranging in parallel a plurality of optical fibers whose surface is coated with a carbon film so that the portions which are to form a connected portion are brought into contact with each other, and by heating the portions which are to form a connected portion in an atmosphere containing oxygen to join these portions by welding while extending the optical fibers. This optical fiber coupler has high hydrogen resistance and static fatigue strength. Also, the use of this coupler provides a small-sized system as a whole without degrading the optical characteristics.
