采用非线性光谱展宽光源作为高重复频率部分相干光载波光源,开展大气湍流信道中高速信息传输实验研究。通过皮秒光纤激光器泵浦高非线性光纤获得非线性光谱展宽的部分相干光载波光源,重复频率可达10 GHz。采用10 Gbit/s脉冲高速数字调制,通过模拟大气湍流信道传输,相干光载波和部分相干光载波在湍流信道传输前后的信噪比分别从16.83 dB和11.83 dB降低至4.31 dB和5.64 dB。在温度差∆T=230℃的模拟大气湍流通道中,当误码率为3.8×10
-3
时,部分相干光载波链路灵敏度达到-27.8 dBm,与相干光载波相比,灵敏度提高了1.6 dB。
The nonlinear spectral broadening light source was used as a partially coherent carrier source with high repetition frequency to carry out experimental research on high-speed information transmission in atmospheric turbulence channels.A partially coherent beams source with nonlinear spectral broadening was obtained by pumping a highly nonlinear fiber with a picosecond fiber laser
and the repetition frequency could reach 10 GHz.The 10 Gbit/s pulse high-speed digital modulation was used and transmitted through a simulated atmospheric turbulence channel
the signal-to-noise ratio of the coherent optical carrier and partially coherent optical carrier before and after the turbulent channel transmission is reduced from 16.83 dB and 11.83 dB to 4.31 dB and 5.64 dB
respectively.In the simulated atmospheric turbulence channel at ∆T=230℃
when the bit error rate is 3.8×10
-3
the sensitivity of partially coherent optical carrier links reaches-27.8 dBm
which is 1.6 dB higher than that of coherent optical carriers.
