| Abstract(in English) | Conversion between multi-valued modulation formats is one of key processing functions for flexible networking aimed at high spectral efficiency in optical fiber transmission. The authors previously proposed an all-optical format conversion system from binary phase-shift-keying (BPSK) to quadrature PSK (QPSK) and reported an experimental demonstration. In this report, we consider its reversed conversion, that is, from QPSK to BPSK. The proposed system consists of a highly nonlinear fiber (HNLF) for wavelength-shift-free four-wave-mixing (FWM) and a 3-dB directional coupler for interference between the incident signal and the generated complex-conjugate signal. The incident QPSK stream is converted into two BPSK tributaries without any loss of transmitting data. The system performance such as bit-error-rate was evaluated by numerical simulation. |
