Summary on Grant Application Form |
|
The proposed programme is a research collaboration between the two UK academia (Leeds and Heriot-Watt), an international fibre drawing laboratory at TNO in Eindhoven and two major international companies in the UK (Nortel & Merck). The objectives discussed above for demonstrating a nonlinear optical fibre in the GeS2 based glass system will be fulfilled by designing glasses for fibre drawing at Leeds and characterising their nonlinear properties at Heriot-Watt. Glasses will be purified for impurities and Merck will support this activity at Leeds. Purified glasses will be drawn into single mode fibres (<1 dB/m loss) at Leeds by adopting double-crucible techniques and at TNO by using rod-in-tube techniques. Losses in the two types of fibres will be compared for making improvements in both processes for fabricating regularly low-loss single-mode fibres. Single-mode fibre will be used for pi-phase switching experiments and n2Lc optimisation at Heriot-Watt and Nortel will undertake system trials. Leeds will also develop the ion-exchange technique for producing short lengths (1-2 m) of low-loss single-mode fibres by using caned GeS2 core glasses.
