NONLINEAR-EFFECT-BASED PATTERN CONVERSION METHOD AND PATTERN CONVERTER

摘要

The embodiments of the present invention provide a nonlinear-effect-based pattern conversion method and pattern converter, relating to the field of optoelectronic communications; silicon waveguide or silicon nanowire cross-phase modulation is used to convert on-off keying (OOK) to phase-shift keying (PSK), the pattern converter comprising: the pump light-generating device and the N first signal light-generating devices are connected one-to-one to the N+1 polarization controllers; said N+1 polarization controllers are connected to the first coupler; said first coupler is connected to the first nonlinear optical waveguide, and said first nonlinear optical waveguide is connected to the filter.
