Intensity-modulated refractometer with long period fiber grating cascaded by chirped fiber grating

Intensity-modulated refractometer with long period fiber grating cascaded by chirped fiber grating

An intensity-modulated refractometer is proposed and experimentally demonstrated by using a long period fiber grating (LPG) cascaded with a chirped-fiber Bragg grating (CFBG). The reflection wavelength band of the CFBG was properly selected to contain the most sensitive spectral part of the LPG. As...
