Dataset for Optical Spectrum with time as temperature is increased for thermally regenerative gratings

Dataset supports:
Jantzen, A. et al (2017). Observations from direct UV written, non-hydrogen loaded, thermally regenerated Bragg gratings in double clad photosensitive fiber. Optics Letters, 42(19), 3741-3744.

Experimental data from the temperature annealing of GF4A fiber annealled in an oxygen environment. A series of Bragg gratings had been written into the fiber prior to heating through the method of Direct Ultraviolet Writing. Continuous data collection from an ANDO AQ6317B optical spectrum analyser, recording on mid sensitivity between 1450 nm to 1600 nm at 0.02 nm resolution. Data is recorded every 24 seconds, corresponding to a 2 degrees celsius increase during ramp. Data is labelled, prerun, for the reference before data collection, run1 for the data once heat is introduced to the system and PostRun is the reference once the experiment had concluded. The references are know to be approximately 4 % reflectors and is used to normalise intensity.
