摘要

提出了一种新的毫米波产生技术。单模激光器发出的光波被分成两个光载流子。其中一个载波通过5ghz微波信号进行相位调制,然后与另一个载波组合。混合光信号经过15公里长的光纤传输后,通过光检测产生由5 ghz微波信号谐波组成的电信号。通过对谐波进行带通滤波,可以得到理想的40ghz毫米波信号。并对该生成方法在下行系统中的数据传输进行了验证。

A novel millimeter-wave generation technique for mm-ROF system based on harmonic generation principle
A novel millimeter-wave generation technique for mm-ROF system is proposed in this paper. The light-wave from single-mode laser is split into two optical carriers. One carrier is phase modulated by 5-GHz microwave signal and then combined with the other carrier. The mixed optical signal after transmission over 15-km-long fiber is photodetected to generate electrical signal consisting of harmonics of 5-GHz microwave signal. The desired 40 GHz millimeter-wave signal can be obtained by bandpass filtering the harmonics. Data transmission on downlink system with the proposed generation method is demonstrated.
