Disclosed is a multi-wavelength hybrid integrated light emitting array, comprising a plurality of light processing units, wherein each of the light processing units comprises: an active optical device (1), including a first substrate (11), with the material of the first substrate being an III-V group semiconductor material and same being used for emitting laser, and a beam splitting optical waveguide (2), including a second substrate (21), with the material of the second substrate being the same as that of the first substrate, and being used for splitting the laser to form beam split laser. The substrates of the active optical device and the beam splitting optical waveguide are the same III-V group semiconductor material, so that optical loss caused by coupling of different materials is reduced, the power consumption of the light emitting array is favorably reduced, and moreover, the preparation process and the size of the multi-wavelength hybrid integrated light emitting array are improved.
