Figure 4
AFM analysis of the optical fiber core region (4 µm × 4 µm top view) of the probes fabricated with MGs concentrations of 0.01% (a), 0.05% (d) and 0.5% (g). AFM images of unpatterned region (2 µm × 2 µm area) of the LOF probes fabricated with MGs concentrations of 0.01% (b), 0.05% (e) and 0.5% (h,c,f,i) slice processing of the MGs thickness of figures (b,e) and (h). Single MG profiles averaged over 10 profiles measured on different areas, and fitted with a quadratic curve (j).
