High-temperature type IIa gratings in 12-ring photonic crystal fibre with germanosilicate core
The inscription of efficient Bragg gratings (> 20 dB) in 12-ring photonic crystal fibre with a germanosilicate doped core without the need for hydrogen loading using 193 nm is demonstrated. We show the characteristic rollover from type I grating to type IIa – the first observation of a type IIa g...
