Other Components


The ready availability of custom-made specialty fibres has enabled many projects on special components; for example wavelength demultiplexors and switches based on twin-core fibre. A current area of research is acousto-optic fibre devices, which hold out the promise of very low cost switches and tuneable filters; components that may be critical to the large scale uptake of fibre in LANs or to the home. Novel fibre designs are increasing the tuning range and decreasing the driving frequency and power.
