摘要

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 fiat-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 2.12nm to 3.06nm,the ROSA responsivity ranges from 0.097 A/W to 0.158A/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.
