Microwave photonic receivers are a promising candidate in breaking the bandwidth limitation of traditional radio-frequency(RF)receivers.To further balance the performance superiority with the requirements regarding size,weight,and power consumption(SWaP),the implementation of integrated microwave photonic microsys-tems has been considered an upgrade path.However,up to now,to the best of our knowledge,chip-scale fully integrated microwave photonic receivers have not been reported due to the limitation of material platforms.In this paper,we report a fully integrated hybrid microwave photonic receiver(FIH-MWPR)obtained by compris-ing the indium phosphide(InP)laser chip and the monolithic silicon-on-insulator(SOI)photonic circuit into the same substrate based on the low-coupling-loss micro-optics method.Benefiting from the integration of all opto-electronic components,the packaged FIH-MWPR exhibits a compact volume of 6 cm3 and low power consump-tion of 1.2 W.The FIH-MWPR supports a wide operation bandwidth from 2 to 18 GHz.Furthermore,its RF-link performance to down-convert the RF signals to the intermediate frequency is experimentally characterized by measuring the link gain,the noise figure,and the spurious-free dynamic range metrics across the whole operation frequency band.Moreover,we have utilized it as a de-chirp receiver to process the broadband linear frequency-modulated(LFM)radar echo signals at different frequency bands(S-,C-,X-,and Ku-bands)and successfully demonstrated its high-resolution-ranging capability.To the best of our knowledge,this is the first realization of a chip-scale broadband fully integrated microwave photonic receiver,which is expected to be an important step in demonstrating the feasibility of all-integrated microwave photonic microsystems oriented to miniaturized application scenarios.
