Negative index gratings formed by a 193nm excimer laser
We have demonstrated fast formation (~1500 pulses at ~1 J/cm<sup>2</sup>/pulse) of fibre gratings with high negative index modulations (~-3×10<sup>-4</sup>). These gratings were found to be far more stable than the gratings with positive index modulations formed at the early...
