Sy. Set et al., ULTRA-HIGH BIT-RATE OPTICAL-PHASE CONJUGATION WAVELENGTH CONVERSION IN DSF AND SOA WITH NOVEL CONFIGURATION INCORPORATING IN-LINE FIBER DFBLASERS, Electronics Letters, 34(17), 1998, pp. 1681-1683
The authors report a novel polarisation insensitive optical phase conj
ugator or wavelength converter using orthogonally polarised fibre dist
ributed feedback lasers as four-wave mixing pumps in both dispersion s
hifted fibre and semiconductor optical amplifiers. Ultra-high bit rate
operation up to 40 Gbit/s and mid-span spectral inversion transmissio
n over 204km of standard fibre is demonstrated.
