| 摘 要： | 基于低速信号注入法-珀(FP)激光器可实现无微波本振光纤无线通信(RoF)上变频技术,但是得到的微波本振频率受到FP激光器中四波混频效率的限制,难以直接实现毫米波载波的RoF上变频。在注入锁定FP激光器的基础上提出了一种新型的、低成本的在光域直接产生毫米波载波的RoF上变频方案。由于注入锁定FP激光器过程中的动态载流子特性,上变频得到的载波信号带有正啁啾,故可用负色散介质对载波信号进行脉冲压缩,从而增强高阶谐波分量以完成毫米波载波的无本振RoF上变频。实验中采用2 Gb/s非归零码注入实现了载波为13.9 GHz,用2.5 Gb/s注入实现了载波分别为13.9 GHz和15.4 GHz的RoF上变频,并采用上述方案分别实现27.8 GHz和30.8 GHz的倍频载波分量的增强。进一步实验验证了用本方案实现载波频率约60 GHz可调谐毫米波的无本振RoF上变频的可行性。

| Abstract: | A novel technique to achieve optical frequency up-conversion in millimeter wave(mm) band without any local microwave oscillator is proposed.It is hard to directly get mm band carrier frequency because the efficiency of mode-locking decreases as the carrier frequency increases.Thanks to dynamic charge carrier density responses during the injection locking of Febry-Perot laser diode(FP-LD),the wavelength of the leading part of carrier is red-shifted while that of falling part is blue-shifted.With a suitable n... |
