摘要： An optical fiber for an optical amplifier, which contains dysprosium ion (Dy3+) with an improved light amplification efficiency at the 1.31 &mgr;m band. The optical fiber includes a germanium-gallium-sulfide (Ge—Ga—S) glass, an alkali metal halide, and Dy as a rare earth element. In the optical fiber, the interaction of electrons of Dy3+ and phonons in the glass lattice can be minimized, so that the multiphonon relaxation of Dy3+0 from 4F11/2 and 6H9/2 to 6H11/2 is slowed down, and thus the fluorescence lifetime at 1.31 &mgr;m is elongated, further improving the fluorescence efficiency of the optical fiber.

摘要： Disclosed is an optical wavelength multiplexer/demultiplexer with uniform loss. The optical wavelength multiplexer/demultiplexer includes a first star coupler for dividing optical power of input optical signals received from input optical waveguides, an arrayed waveguide grating for guiding the optical signals outputted from the first star coupler therethrough in such a fashion that the optical signals have different phases, respectively, a second star coupler for coupling or dividing the wavelengths of the optical signals outputted from the arrayed waveguide grating, and outputting the resultant optical signals to output waveguides, respectively, and a waveguide mode controller for controlling the profile of a waveguide mode of the optical signals outputted from the arrayed waveguide grating, thereby allowing the optical signals focused at an output terminal of the second star coupler to have flat amplitude distributions. The waveguide mode controller maintains the main peak of the output waveguide mode while phase-shifting tails of the output waveguide mode. By virtue of the mode controller, it is possible to form a diffraction pattern with flat amplitude distribution. Accordingly, an uniformity of loss among channels is obtained.
