The future of fibre circuitry.
In, The Rank Prize Funds Mini Symposium on Optical Amplifiers, Grasmere, United Kingdom,
27 - 30 Apr 1992.
Although functional, interconnected, multi-path fibre devices (fibre circuits) have been around for some time, the development of the EDFA has given enormous impetus to the area, since the inclusion of an active element allows far greater versatility. Already a number of quite complex circuits have been reported for non-linear switching, soliton-generation, logic, multiplexing and demultipexing and a wide variety of fibre-lasers. To date, with the exception of the EDFA itself, the impact on current telecommunications networks has not been great, owing largely to the advanced nature of the devices, such as their very high bit-rate capability. It is therefore interesting to speculate on the future of fibre circuitry in the high-capacity telecommunications environment of the future
