We present an array of GaAs QD III-V-on-Si DFB lasers integrated by micro-transfer printing. An alignment tolerant III-V/Si taper structure is used to evanescently couple light from the laser cavity to the underlying 400 nm thick rib waveguide. Single mode operation around 1300 nm with 48 dB side mode suppression ratio and a waveguide-coupled power of 0.5 mW is demonstrated.
