<P>PROBLEM TO BE SOLVED: To provide a multiple-wavelength batch monitoring method and device which can be located on a transmission line, and be used in place of functions of an optic spectrum analyzer by combining cheap optical parts. <P>SOLUTION: The device uses a tunable filter 9, which is used in micromachines or planar lightwave circuit (PLC) and has advantages in costs and productivity, and has a calibrated standard light source 10 inside for compensation of temperature drift of such devices. Therefore, the device can be provided on a transmission line, and be used in place of functions of an optic spectrum analyzer by combining cheap optical parts. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
