Research output: Contribution to journalJournal articleResearchpeer-review


liquid filling of photonic crystal fibres reduces the scattering from air–glass interfaces during Bragg grating writing in many layered photonic crystal fibres. Within experimental uncertainty, the grating index modulation of a grating written in germanium-doped photonic crystal fibre with 10 rings of holes was more than doubled for a fixed fluence.
