Planar silica device technology provides the ability to filter, route, switch, and attenuate optical signals for Wavelength Division Multiplexing (WDM) based photonic networks. As network capacity expands there is a requirement to increase the comple

This paper studies the acousto-optic interaction induced by an acoustic flexural wave among the optical propagation modes supported by tapered optical fibres. We have investigated the evolution of the acousto-optic resonance condition as the fibre is

Nonreturn-to-zero (NRZ)- and return-to-zero (RZ)-transmission formats are investigated for 1.55 /spl mu/m 40 Gb/s fiber grating dispersion compensated standard fiber transmission. The RZ-format is shown to give a twofold increase in transmission dist

We report the first experimental demonstration of the optical pushbroom - a novel type of all-optical pulse compression. In the optical pushbroom high intensity pump pulses, tuned well away from the resonance of a Bragg grating, modify the transmissi

We compare the performance of dispersion-shifted-fibre (DSF) and semiconductor-optical-amplifier (SOA) based phase conjugators for a 10 Gb/s non-return-to-zero system with respect to conversion efficiency, noise figure and distortion. Fibre gratings

We demonstrate for the first time a 1.49µm Er3+:Yb3+ co-doped silica fiber laser with fiber Bragg grating feedback, pumped with a diode-pumped Nd:YLF laser at 1.047µm, which can be used for remote pumping of EDFAs. We examine both the potential and

The optical properties of praseodymium-doped low-phonon-energy glasses have recently attracted considerable attention for their potential application as a 1.3 μm Pr +3 -doped optical fibre amplifier. Sulphide glasses based on Ga 2 S 3 and La 2 S 3 a

A composite-EDFA configuration which incorporates an optical isolator has been investigated theoretically and experimentally. The isolator prevents the build-up of the backward-ASE and results in an amplifier with high gain and near-quantum-limited n

The effect of the internal Rayleigh scattering on the gain efficiency and noise of the erbium-doped fiber amplifier has been considered in detail. It is shown that excess background loss due to Rayleigh scattering at the signal and pump wavelengths d
