摘要

摘要本文报告了利用双并行马赫-泽恩德调制器和半导体光放大器产生 30 倍毫米波的光纤无线电系统。马赫-泽恩德调制器参数的最佳选择产生了频率间隔为 10fRF 的信号光波和泵浦信号。半导体光放大器中的四波混合效应产生了 30 倍的毫米波信号。所提出的方案适用于有多个基站的光纤无线电系统。仅使用 5 GHz 无线电频率就能产生 50 GHZ、100 GHz 和 150 GHz 等多个频率。2.5 Gbps 的 NRZ 数据经调制后通过光纤成功传输。研究了注入电流对边带比和误码率的影响。所提出的方案在 20 千米的传输距离内确认了解调信号的接收质量。

MZM–SOA based RoF system for 30-tuple millimeter-wave generation

Abstract In this paper, we have reported radio over fiber system with 30-tuple millimeter-wave generation using dual parallel Mach–Zehnder modulator and semiconductor optical amplifier. The optimum choice of Mach–Zehnder modulator parameters has resulted into generation of signal lightwave and pump signal with frequency separation of 10fRF. Four wave mixing effect in semiconductor optical amplifier results into 30-tuple millimeter-wave signal. The proposed scheme is applicable to radio over fiber system with multiple base stations. The multiple number of frequencies such as 50 GHZ, 100 GHz, and 150 GHz have been generated using 5 GHz radio frequency only. NRZ data at 2.5 Gbps was modulated and successfully transmitted via optical fiber. The impact of injection current on the sideband ratio and BER is investigated. The proposed scheme confirms quality reception of demodulated signal at a transmission distance of 20 km.
