【Abstract】 Variable optical attenuator(VOA)is one of the key devices in Dense Wavelength Division Multiplexing(DWDM)network.The paper propose a designing method of a novel polymer based VOA,which utilize the thermo optic effect of polymer and achieve 25dB attenuation range.The novel polymer VOA is attractive in practice due to its compact size,low insertion loss,low cost and low power consumption,in addition,it shows good polarization independence.The author made analysis and simulation on some qualities of the device in this paper.更多还原
