    摘要: An arrayed waveguide grating (AWG) wavelength division multiplexer (WDM) provided with alignment waveguides, and an apparatus for aligning the arrayed waveguide grating wavelength division multiplexer. The wavelength division multiplexer is provided with alignment waveguides, to be used upon coupling the optical waveguide device to optical fiber blocks, in addition to waveguides required for achievement of desired functions, so that it can achieve a desired alignment irrespective of the achievement of those functions. Accordingly, it is unnecessary to know respective operation characteristics of individual devices, thus easy and rapid alignment and bonding can be achieved. In accordance with the present invention, the operation wavelength of the optical wavelength device can be determined by detecting the wavelength of the light output from each alignment waveguide. Accordingly, it is possible to simply determine whether or not the optical waveguide device operates normally.

    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.
