Simulations for analysis of the effect of ZnO-coated fiber grating structure to the Bragg wavelength
This paper theoretically analyses the characteristic of a fiber Bragg grating coated with piezoelectric zinc oxide (ZnO) in order to operate under the acousto-optic effect by means of shifting Bragg wavelength. Simulations are performed to investigate the change of Bragg wavelength when varying parameters of the device structure. The results will be useful for consideration of device design as well as determination of the operating conditions
