| 中文摘要 | 报道了一种插入马赫-曾德尔(M-Z)光纤干涉仪的半导体光放大器(SOA)多波长光纤环形激光器,实现了信道间隔为100 GHz的稳定的多波长连续光激射,其输出光谱3 dB带宽为19.5 nm,消光比大于30 dB.其中在17.9 nm范围内获得了22个波长的连续光,功率不平坦度为1.2 dB,总输出功率为5.1 dBm.对该结构的多波长激光器输出光谱宽,不同波长间功率波动小的特性进行了分析,提出在较低环腔损耗下,半导体光放大器的增益饱和及四波混频(FWM)效应的共同作用使环腔内多波长光功率获得自动均衡;并对实验观测到的激光器输出光谱带宽及中心波长随半导体光放大器驱动电流降低或环腔损耗增大而减小的现象进行了讨论.; A semiconductor optical amplifier(SOA) multi-wavelength fiber ring laser with a Mach-Zehnder(M-Z) fiber interferometer was reported and stable multi-wavelength continuous-wave lasing oscillations with channel spacing of 100 GHz are achieved with the 3 dB spectral bandwidth of 19.5 nm and signal-to-noise ratio higher than 30 dB.It is observed that the output power variation of the 22 wavelengths in 17.9 nm is 1.2 dB and total output power is 5.1 dBm.The wide spectrum and low output power variation acquired in this laser are attributed to the self-averaging of multi-wavelength optical power induced by gain saturation and four-wave mixing(FWM) in SOA under the low cavity loss condition.The decrease of the spectral bandwidth and center wavelength with the decrease of driving current of SOA or the increase of cavity loss observed in the experiment was also discussed.; 国家自然科学基金(60477021)资助项目 |
