The purpose of the present invention is to provide an optical wavelength power meter having low manufacturing and maintenance costs. An optical wavelength power meter according to one embodiment of the present invention comprises: one or more arrayed waveguide gratings for outputting an optical signal with multiplexed wavelengths into optical signals with a single wavelength; and a detector for receiving the optical signals with a single wavelength outputted from the arrayed waveguide gratings. The detector may consist of arrayed optical sensors, each optical sensor of which can receive each signal with a single wavelength, or the detector may consist of a plurality of optical sensors, each optical sensor of which can receive each optical signal with a single wavelength, wherein each of the plurality of optical sensors may be directly connected to each output unit of the arrayed waveguide gratings or connected to each output unit of the arrayed waveguide gratings via an array of optical fibers. In addition, the detector may include a rotation plate having a plurality of coupling units, each of which is coupled to each of output units of the arrayed waveguide gratings; and an optical sensor for receiving an optical signal with a single wavelength from one of the plurality of coupling units. |
