WebAbstract By monitoring the wavelength-shift of Bragg-resonances in a fibre grating during cladding-etching, we measure the refractive-index of buffered-HF acid (20:1) as 1.36±0.005 @ 1.55μm, and use that to demonstrate precise control the fibre etch-diameter. © 2015 Optical Society of America PDF Article Web30. máj 2024 · Results showed that doping with HCl and H2 SO4 acidic mediums caused a reduction in the direct energy gap of the pure PANI from 2.69eV to 2.42 eV and 2.54 eV, respectively. The reduction in optical energy gap is associated with the increase in refractive index. The refractive index (2.92) has a higher value of PANI doped with HCl.
