Defect production in silica fibers doped with Tm³⁺

Irradiation of Tm3+ fibers with blue light at 476 nm induces a broad-bandwidth loss in these fibers. We have measured the spectral dependence of the loss for both silica-germania and silica-alumina fibers and show through micro-Raman studies of the core regions of the fibers that this induced loss is correlated with the production of structural defects in the glass host

Limitations in long haul IM/DD optical fibre systems caused by chromatic dispersion and nonlinear Kerr effect

The power penalty induced by dispersion, Kerr nonlinearity and attenuation is numerically investigated for long haul IM/DD systems with cascaded optical amplifiers. We demonstrate that the eye opening is critically dependent on the input mean power.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Effects of chromatic dispersion, Kerr nonlinearity and amplifier noise in long PSK optical fibre systems.

The power penalty induced by dispersion, Kerr nonlinearity, attenuation and amplifier noise is numerically investigated for long 6000 km amplified PSK systems. We demonstrate that transmission is only possible in the normal dispersion domain.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
