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.
