摘要： PROBLEM TO BE SOLVED: To provide a waveguide type variable optical attenuator which stops the increase in polarization dependent loss dispersion according as the attenuation rate increases, which can acquire attenuation rate of 30dB or more by this, and which suppresses the power consumption. SOLUTION: Even when the difference of the attenuation rate (PLD: polarization dependent loss dispersion) occurs between a vertical polarization and a horizontal polarization in a channel waveguide 5a in a first symmetric Mach-Zehnder optical circuit 10a, the horizontal / vertical ingredients are exchanged by a polarization maintaining fiber 12, and income into a second symmetric Mach-Zehnder optical circuit 10b. As the difference of the attenuation rate occurs in the second symmetric Mach-Zehnder optical circuit 10b as well, the PDL occurred in the first symmetric Mach-Zehnder optical circuit 10a is offset in the second symmetric Mach-Zehnder optical circuit 10b.
