| Abstract(in English) | Flexible conversion between multi-level modulation formats is one of the key processing functions to realize adaptive modulation techniques for flexible networking aimed at high spectral efficiency in optical fiber transmission. The authors have proposed an all-optical format conversion system from quadrature phase-shift keying (QPSK) to binary PSK (BPSK). It had an advantage of wavelength-shift-free conversion from an incident QPSK to simultaneous two BPSK outputs without loss of the transmitting data. However, it was limited only for a single polarization signal. In this paper, we propose a novel method for polarization division multiplexed QPSK signal based on the orthogonal dual-pump four-wave-mixing (FWM) in the highly nonlinear fiber with a nonlinear optical loop mirror configuration. We show the system performances such as bit-error-rate and optical signal-to-noise ratio penalty evaluated by numerical simulations. |
