  • Abstract
    A temperature-insensitive dual-comb filter has been demonstrated for the first time by multimode interference based on a Ti:LiNbO3 channel waveguide. The phase difference between comb filters was about 180deg. We only observed less than plusmn0.125-nm variation of the center wavelength of the filter during temperature change from 20degC to 50degC. The measured extinction ratio and channel spacing of the comb filter were about -25 dB and 3.2 THz, respectively.
