We use the GN-model to assess Nyquist-WDM 100/200Gbit/s PM-QPSK/16QAM signal reach on low loss, large core area fibre using extended range, variable gain hybrid Raman-EDFAs. 5000/1500km transmission is possible over a wide range of amplifier spans.

The design of a high-power low-divergence low-astigmatism tapered-waveguide laser array is described. A two-dimensional beam propagation model is used for the first time to optimize a tapered-waveguide laser, which includes full thermal and spatiotem

The non-linear response of fluorescein-doped boric acid glass was probed using the Z-scan technique. A striking contrast was observed in its non-linear transmission characteristics at different argon-ion laser wavelengths. The non-linear transmission

Synthesis of a sharp switching characteristic is experimentally demonstrated by concatenation of nonlinear optical loop mirrors. A novel configuration has been used which results in three terminal operation of the device. This device can be used as a

A fiber-based device with a novel nematic liquid-crystal overlay compatible with silica fiber at room temperature is reported here to demonstrate polarization-independent modulation. The device is formed using a polished half-coupler block that has b

All-optical switching is of increasing interest for ultrafast transmission systems and logic applications. Silica fibres are particularly attractive for fabrication of switching devices since the nonlinearity is ultrafast and losses are low. A number
