摘要

提出了一种将低速基带信号直调产生的宽谱信号，注入至用于上变频的分布反馈式半导体激光器(DFB-LD)，利用调制信号光谱中的高阶分量对从激光器进行相位锁定，从而产生光学上变频信号的方法。对直调信号注入锁定DFB-LD产生光学上变频信号的机理进行了理论分析，完成了2.5 Gb/s伪随机码基带信号通过直调并注入从激光器，分别产生了30，35，40 GHz副载波频率的全光上变频信号的实验，并在时域和频域上，对上变频信号的特征进行了研究。该方案结构简单，无需高速外调制器及高频本振，具有集成潜力，理论上可产生更高载频(如60 GHz)，对目前的光无线混合接入提供了一种可行的解决方案。

Abstract

A novel scheme of optical frequency up-conversion is proposed by using the high order sideband of the directly modulated low-speed baseband signal for injection locking of a distributed feedback semiconductor laser (DFB-LD). The operational principle of the proposed optical frequency up-conversion scheme is theoretically analyzed. Based on this scheme, optical frequency up-conversion of a 2.5 Gb/s is directly modulated baseband signal to 30, 35 and 40 GHz subcarrier modulation signal respectively. Higher carrier frequency (up to 60 GHz) can also be achieved in potential. The proposed scheme does not need expensive components like high-speed external modulator or high frequency radio frequency (RF) local oscillator, and it has the benefit of simple structure. It provides a viable solution for the optical-wireless hybrid access.
