Paper Abstract

Long period fiber grating (LPFG) has been attracted much attention for use in optical sensing applications and optical communication systems. Compared with a regular LPFG, the phase shift long period fiber grating (PS-LPFG) has shown certain unique advantages such as higher sensitivity and potentials for simultaneous measurements of multiple parameters. This paper presents the fabrication and characterization of PS-LPFG by CO2 laser point-by-point irradiations. We emphasis on the difference between LPFG and PS-LPFG as optical sensors for measurement of strain, temperature and refractive index.
