The digital coherent receiver realizes phase synchronization in the digital domain and can demodulate any multilevel coded optical signals. However, the maximum symbol rate processed by such receiver is limited by the speed of electric ADCs and DSP. Although real-time operation at 10 Gsymbol/s using a digital coherent receiver has recently been demonstrated, it is still difficult to increase the symbol rate beyond 40 Gsymbol/s. In order to cope with this difficulty, we propose a novel scheme, which employs an LO pulsed at the subharmonic frequency of the symbol rate, enabling optical time-division demultiplexing of the signal at the digital coherent receiver. We demonstrate that the new type of digital coherent receiver operating at 10 Gsymbol/s can demodulate the aggregate symbol rate of 160 Gsymbol/s. |
