| Abstract(in English) | The new technology called Digital Coherent Optical Communications has recently emerged, combining ultrafast digital signal processing and coherent optical technologies. Such technology enables multi-level optical modulation and polarization-division multiplexing, because we can achieve carrier-phase recovery and polarization alignment in a stable manner in the digital domain; thus, we can obtain the single-channel transmission capacity as high as 100 Gbit/s, introducing the dual-polarization quadrature phase-shift keying (DP-QPSK) modulation format. Moreover, we can compensate for linear impairments stemming from group-velocity dispersion and polarization-mode dispersion of fibers, using adaptive equalizers implemented in the receiver. In this tutorial lecture, we talk about the fundamentals of digital coherent optical communications including optical circuits and digital signal-processing units in the receiver. |
