Index matched grating inscription

摘要

The disclosed embodiments provide systems and methods for mitigating lensing and scattering as an optical fiber is being inscribed with a grating. The disclosed systems and methods mitigate the lensing phenomenon by surrounding an optical fiber with a liquid index-matching material that is held in a vessel. The disclosed systems also include a replenishment mechanism that replenishes the liquid index-matching material as the optical fiber is pulled through the vessel.
