摘　　要：为了成倍地提高通信系统的传输容量,采用10 km少模光纤构建3×3模分复用实验平台,模式的转换及复用通过模式选择性光子灯笼实现,以相位调制-相干接收方式完成光信号的调制与检测,最终实现3×34 Gb/s偏振复用—正交相移键控(PDM-QPSK)信号的有效传输。研究结果表明:如果保持LP_(01)、LP_(11)和LP_(21)的接收功率不低于-25.32 dBm,可以使误码率始终低于10^(-3)。In order to increase the transmission capacity of communication system exponentially,a 3×3 mode division multiplexing experiment platform is constructed using 10 km few-mode optical fiber,the mode conversion and multiplexing are realized by the mode-selective photon lantern,and the modulation and detection process is carried out in the phase modulation-coherent receiving mode,and the effective transmission of the 3×34 Gb/s polarization division multiplexed-quadrature phase shift keying(PDM-QPSK)signal is finally completed.The results show that if the received power of LP_(01),LP_(11) and LP_(21 )is not less than-25.32 dBm,the bit error rate can be certainly reduced to less than 10^(-3).
