Novel multi-channel and nonlinear Bragg grating devices. High capacity and reliable telecommunications links are essential for many aspects of modern life and work. Optical fibres offer essentially unlimited capacity, but their optimal use requires the transmission of multiple wavelength channels simultaneously. This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. ....Novel multi-channel and nonlinear Bragg grating devices. High capacity and reliable telecommunications links are essential for many aspects of modern life and work. Optical fibres offer essentially unlimited capacity, but their optimal use requires the transmission of multiple wavelength channels simultaneously. This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. Fibre Bragg gratings are central to many of these devices, and the aim of this project is to develop novel designs for linear and nonlinear Bragg grating devices which may significantly widen the current range of their applications.Read moreRead less
Mechanical stresses in holey fibres. The development of holey fibres constitutes arguably the most exciting development in fibre optics in recent years. We will analyze the mechanical stresses in these fibres, which, together with the optical calculations and associated experiments, will allow us to design novel fibre-based devices. This will allow Nufern to develop new products based on holey fibres.
Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre. Current optical fibre networks use only a fraction of their capacity. This is in part because optical amplifiers with enough bandwidth do not exist. However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric ampli ....Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre. Current optical fibre networks use only a fraction of their capacity. This is in part because optical amplifiers with enough bandwidth do not exist. However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric amplifier with a world record bandwidth, which will enable the full capacity of optical fibre to be exploited.Read moreRead less
