An 8 × 10 GHz receiver optical sub-assembly(ROSA)consisting of an 8-channel arrayed waveguide grating(AWG)and an 8-channel PIN photodetector(PD) array is designed and fabricated based on silica hybrid integration technology. Multimode output waveguides in the silica AWG with 2% refractive index difference are used to obtain flat-top spectra. The output waveguide facet is polished to 45` bevel to change the light propagation direction into the mesa-type PIN PD. which simplifies the packaging process. The experimental results show that the single channel 1 dB bandwidth of AWG ranges from 2.12 nm to 3.06 nm, the ROSA responsivity ranges from0.097 A/W to 0.158 A/W and the 3 dB bandwidth is up to 11 GHz. It is promising to be applied in the eight-lane WDM transmission system in data center interconnection.
