Abstract

Disclosed are a dual-carrier integrated optical device and a photoelectric module. The optical device comprises: an encapsulation unit, and a ceramic substrate and two independent carrier assemblies arranged in the encapsulation unit. Every carrier assembly comprises a DWDM active chip arranged on the first heat sink, a first heat sink arranged on the independent control element, and an independent control element for adjusting the temperature of the DWDM active chip to adjust an output wavelength of the DWDM active chip. The DWDM active chip and the independent control element are respectively connected to the ceramic substrate. According to the characteristic that the wavelength of the active chip will shift with the temperature, an output laser wavelength of each active chip is independently controlled by means of the independent control element, which achieves higher wavelength stability and can realize optical signal transmission at different rates.
