A novel dispersion compensating microstructured fibre design is proposed. The fibre has a honeycomb cladding structure with an up-doped core region, and is designed to match the relative dispersion slope of standard single-mode fibre. A dispersion va

Although patterning effects (PEs) are known to be a limiting factor of ultrafast photonic switches based on semiconductor optical amplifiers (SOAs), a simple approach for their evaluation in numerical simulations and experiments is missing. In this w

The feasibility of transmitting 0.87 Tbit/s dual polarization D8PSK-OTDM over 110 km is, for the first time, demonstrated along with 0.44 Tbit/s single polarization D8PSK-OTDM over 220 km in conventional 55-km span SMF+DCF link.
