Tapered Long Period Gratings

OFS_2017_TLPG_Fig2.xlsx. Figure 2 from Proc. SPIE 10323, 10323C. The spectrum of a tapered long period grating after the fabrication of each of the tapered sections, where the waist diameter was 117 μm and the period was of 418 µm. The TLPG was fabricated in Fibrecore SM750 fibre, and the spectrum recorded using an Ocean Optics CCD spectrometer.
