Abstract
Aiming at the practical requirements of photodetector arrays with integrated power combiners for microwave pho-tonic systems,a high-consistency photodetector array based on photoelectric hybrid integration packaging technology is de-signed.The proposed method is carried out from three dimensions:optical path design,radio frequency link design,and pack-aging structure design.Channel consistency is enhanced by precisely controlling the tolerance of fiber length and by screening and matching the gain and phase of radio frequency chips such as low-noise amplifiers and equalizers.Experimental results show that the array operates over a frequency range of 2～18 GHz.The single-channel gain is greater than-13.7 dB,with a chan-nel gain consistency of±0.3 dB.The phase consistency is better than±13.82°,and after deducting the difference in fiber length,the electrical phase consistency is better than±2.75°.Power combination simulations based on measured data indicate that the combined gain is greater than-7.6 dB,with a relative power combination efficiency exceeding 97.5%.After compensating for fiber length differences,the average efficiency reaches 99.83%.关键词
