Abstract :
We propose and demonstrate a novel technique for optical wavelength conversion and phase conjugation by fiber four-wave mixing using inline fiber distributed-feedback lasers as orthogonally polarized pump sources. This technique features polarization independent operation and a simple all-fiber configuration without the need for externally injected pumps. Polarization dependency as low as 0.5 dB has been achieved using this technique.
