摘　　要：文中提出在高频光电系统中，仅用一只雪崩光电二极管（ＡＰＤ）来同时完成光电检测、信号放大和射频（ＲＦ）混频．从理论和实验两个方面都力。以证明，ＡＰＤ光电外差检测技术是成功和有效的，此外还对ＡＰＤ工作参数进行了优化．Optoelectronic heterodyne detections plays an important role in a high-frequency optoelectronic system. It is generally accomplished by a photodetector and an RF-mixer. In this paper, a new technique is presented by which photodetection amplification and RF-mixing can be carried out by only one APD (aValanche photodiode).Theoretical analysis and experiments show that this technique is successful and efficient.Finally,operation parameters of APD are optimized by computer.
