Waveguide quasi-phase-matching (QPM) twin photon generation (TPG) devices are the key device for future quantum communication. We examined the temperature dependences of the twin photon wavelengths of a MgO:LiNbO3 waveguide Type-I QPM TPG device to clarify the possibility of twin photon wavelength tuning. It turned out that, in a typical device of 19 mu m QPM grating period for TPG in the 1.55 mu m band, twin photon wavelength tuning ranges of similar or equal to 16 and 300 nm can be obtained for degenerate and nondegenerate TPG, respectively, with temperature control in 25-150 degrees C.
