Realizace laditelného filtru založeného na Braggovských mřížkách

Abstract

The bachelor theses is dealing with the subject of optofibre Fiber Bragg grating, which is used throught the whole field of optics. The main aim of the theses, based on theoretical findings which are described in the first three chapters, is to design and implement a tunable filtre based on Bragg‘s grid. The design and implementation is, in the final part, completed by experimental verification of the functioning of the tunable filter. Theoretical part, which is divided into several chapters, is dealing with the optical Bragg´s grid, it‘s manufacture, parametres and usage in the optical fibres. Second chapter is dedicated to optic filters, it‘s manufacture and division. The last, third chapter of the theoretical part is describing Peltier´s segment, which is used in the practical part of the bachelor theses. The functioning of the tunable filter is experimentaly verified in the practical part of the theses. Specifically the sensitivity and range of the setting of the wavelenght.
