An embodiment of the invention provides a dual carrier integrated optical device and a photoelectric module. The device comprises a package unit, and a ceramic substrate and two sets of independent carrier components arranged in the package unit. Each set of the carrier components comprises a DWDM active chip, a first heat sink, and an independent control element. The DWDM active chip is arrangedon the first heat sink. The first heat sink is arranged on the independent control element. The DWDM active chip and the independent control element are respectively connected to the ceramic substrate. The independent control element is used to adjust the temperature of the DWDM active chip to adjust the output wavelength of the DWDM active chip. According to the characteristic that the wavelengthof the active chip will shift with the temperature, the laser wavelength of each active chip separately is controlled by an independent control element in the embodiment of the invention, so that thewavelength stability is high, and optical signal transmission at different rates can be realized.
