    摘要: A light source device comprises a light source for outputting a light having the first wavelength; a first lens for converting the light into a collimated beam; an optical output unit for outputting a light having the second wavelength; a second lens for converting the light into a collimated beam; and an optical filter, provided between said first lens and the second lens, for passing the light having the first wavelength and reflecting the light having the second wavelength. The optical input unit receives the lights having the first and the second wavelengths collected by the second lens, and outputs a light wavelength-multiplexed through the optical input unit. An optical amplifier is designed by directly connecting a rare earth doped optical fiber to the output side on which a wavelength-multiplexed light of the light source device is output. A wavelength-multiplexed light source can be also designed by serially connecting plural stages of light source devices. In the optical fiber amplifier, a loss generated between a pump light source and a rare earth doped optical fiber can be reduced, and the reduction of a gain can be prevented. Thus, the entire system including the optical fiber amplifier can be much smaller.

    摘要: In an optical switching device, an optical medium such as a prism and a glass plate is rotatively held on a supporting member by a pivot bearing and a pivot shaft, and the optical medium is rotated, for instance, by a magnetic force so that optical paths are mechanically changed-over. For this construction, the area of the frictional contact surfaces between the pivot bearing and the pivot shaft is decreased thereby providing a stable dynamic characteristic which is maintained for a long time.
