Optical variable attenuators are one of the most important components in dense wavelength division multiplexing networks. A new design method of polymer photo-variable attenuator (VOA) is introduced, which utilizes the thermo-optic effect of polymer and its dynamic range is up to 25 dB. The new polymer VOA not only has the advantages of small size, low insertion loss, low power consumption, but also shows good polarization independence. The related performance analysis and simulation of the device
