Process for the production of polarisation-retaining optical fibres |
| 摘要 |
The invention relates to a process for the production of polarisation-retaining optical fibres which have an essentially elliptical cross-section. This cross-section is achieved by maintaining or adjusting a certain gas and/or vapour (reduced) pressure within the preform during the fibre drawing operation.
