Oppositely-biased dual-polarization IQ modulators for nonlinearity-tolerant polarization-multiplexed phase-conjugated twin-signals generation

摘要

We experimentally demonstrate generation of polarization-multiplexed phase-conjugated twin signals by using oppositely-biased dual-polarization IQ modulators, compensating for nonlinear signal distortion in fiber transmission. Bias condition is optimized investigating nonlinearity tolerance of the generated signals transmitted over SMF.
