Novel time domain add/drop multiplexer based on double-pumped four-wave-mixing and cross-phase-modulation induced spectral shift in a semiconductor optical amplifier

摘要

Channel extraction and clearing for an all-optical add/drop multiplexer is demonstrated in a novel configuration exploiting both four-wave-mixing and cross-phase-modulation in a single semiconductor optical amplifier. The scheme is insensitive to signal input polarization and wavelength.
