摘要:
理论分析了线宽对受激布里渊散射阈值的影响,使用噪声信号直接调制分布反馈半导体激光器构成可调线宽激光光源,搭建了受激布里渊散射阈值测量系统. 结果表明,可调线宽激光的频谱与所使用的噪声信号的频谱类似,光谱与分布反馈半导体激光器输出光的光谱相比明显展宽. 当可调线宽激光光源使用400 mV噪声信号进行调制时,长度为900 m单模光纤的受激布里渊散射阈值为616 mW,与使用DFB激光器测量的106 mW阈值相比,提高了7.6 dB. 因此,可调线宽激光光源可以提高光纤的受激布里渊散射阈值,增加长距离光纤通信和光载电能传输系统中的光功率.
Abstract:
The influence of laser linewidth on a stimulated Brillouin scattering threshold is analyzed theoretically, and a linewidth variable laser source made of noise-modulated distributed-feedback semiconductor laser is used in the stimulated Brillouin scattering threshold measurement system. Experimental results show that the power spectrum of the linewidth variable laser source is similar to that of the noise signal used in the experiment, and the optical spectrum is broadened significantly compared with that of the distributed-feedback semiconductor laser. When the noise amplitude used in the linewidth variable laser source raises from 0 to 400 mV, the threshold of stimulated Brillouin scattering in a 900 m single-mode fiber increases by 7.6 dB, from 106 to 616 mW. Therefore the proposed method can be applied to increase the stimulated Brillouin scattering threshold effectively thus increasing the transmission light power in long-distance optical fiber communication system and the power over fiber system.
