Měření útlumových parametrů optického coupleru po gama ozáření

Abstract

The bachelor thesis studies a passive optical splitter or coupler. The aim is to determine the effect of gamma radiation on attenuation parameters of the coupler, including theoretical analysis of device. The theoretical part provides basic information related to the issue coupler. The practical part deals with the measurements of the impact of gamma radiation on the attenuation parameters of the coupler. The essential parameters of the measurement are insertion loss, split ratio, total losses, homogeneity of the losses and directionalities. The work is based on the assumption of an increase loss and its subsequent decline consequently of relaxation of the material. It is a primeval view of this the problem.
