Abstract

We experimentally demonstrate a duplex millimeter-wave-over-fiber (MMWoF) link for duplex wireless communications using a free-running InAs/InP quantum-dash passively-mode-locked laser (QD-MLL) as a light source. The QD-MLL is able to generate a frequency comb with a comb spacing of 0.2 nm (25.08 GHz). In the downlink, a microwave vector signal at 3 GHz is modulated on one comb line and transmitted with an adjacent comb line to a remote radio unit over a 10-km single-mode fiber. After detection at a photodetector, a microwave vector signal at an up-converted frequency of 28 GHz is generated and radiated to achieve 2-m wireless transmission. In the uplink, a microwave vector signal at 28 GHz is down converted to 3 GHz and modulated on a reused comb line and transmitted to the central office over the same fiber link. The performance in terms of the error vector magnitudes and bit error rates is evaluated experimentally.

使用InAs/InP量子冲刺锁模激光器的光纤链路双工毫米波
我们实验展示了一种双工毫米波光纤(MMWoF)链路,用于双工无线通信,使用自由运行的InAs/InP量子短跑无源锁模激光器(QD-MLL)作为光源。QD-MLL能够产生梳间距为0.2 nm (25.08 GHz)的频率梳。在下行链路中,3ghz的微波矢量信号在一条梳状线上调制,并通过相邻的梳状线通过10公里的单模光纤传输到远程无线电设备。经光电探测器检测后,产生上变频频率为28ghz的微波矢量信号并辐射,实现2m的无线传输。在上行链路中,28ghz的微波矢量信号向下转换为3ghz,在重复使用的梳状线上调制,并通过同一光纤链路传输到中心局。从误差矢量大小和误码率两方面对其性能进行了实验评价。
