Opto-elastic properties of FBG based fabryperot resonator: Fabrication, characterization, and applications / Md. Rajibul Islam

Fiber Bragg Gratings (FBGs) are highly sensitive to acousto-optic wave, temperature, pressure wave, and etc. FBGs are used in our study to manufacture all fiber Fabry-Perot resonator (FPR) in different optical fibers. The variations in grating pitch and refractive index of the fiber device are the k...

Moreover, the background study on the widespread theory of opto-elasticity, the correlation of refractive index and stress, in silica based optical fiber is presented. In this thesis, the fabrication and characterization of FBG based short cavity FPR and PCF cavity FPR are demonstrated. In addition, opto-elastic properties of FBG based FPR in various fibers are studied under the influence of longitudinal waves, pressure and temperature through simulation and experimental investigation.

Both spatial modes can be concurrently excited using a phase plate at different intensity ratio of LP01:LP11 in the TMF. Diverse interference patterns are formed in the output spectra by the excited input beams.
