The reflection wavelength band of the CFBG was properly selected to contain the most sensitive spectral part of the LPG. As a result, intensity of the reflected signal was modulated linearly by refractive index (RI) of surrounding liquid outside the LPG. RI measurement in a range from 1.33 to ~1.45 was realized with enhanced sensitivity up to 48.93 μW/R.I.U. | URI: | https://hdl.handle.net/10356/88786 http://hdl.handle.net/10220/46970 |
