High bitrate operation of a novel optical phase conjugator using inline fibre DFB lasers

We report the first demonstration of high bitrate, polarisation insensitive optical phase conjugation and wavelength conversion using orthogonally polarised fibre distributed feedback lasers as four-wave mixing pumps in both dispersion shifted fibre and semiconductor optical amplifier

Ultra-high bitrate optical phase conjugation/wavelength conversion in DSF and SOA with a novel configuration incorporating inline fibre DFB lasers

The authors report a novel polarisation insensitive optical phase conjugator or wavelength converter using orthogonally polarised fibre distributed feedback lasers as four-wave mixing pumps in both dispersion shifted fibre and semiconductor optical amplifiers. Ultra-high bit rate operation up to 40 Gbit/s and mid-span spectral inversion transmission over 204 km of standard fibre is demonstrated

Cord blood collection and banking from a population with highly diverse geographic origins increase HLA diversity in the registry and do not lower the proportion of validated cord blood units: experience of the Marseille cord blood bank.
