Measurement of the Energy propagation in Optical Splitters due to High-Power and Gamma Radiation Load

In the article, ageing degradation processes on photonic splitters (1:2) are studied. One splitter is loaded by gamma radiation (60Co) and the other by a high-power load (stepped Er3+ amplifier). An evaluation is performed by BP109-IR device through an energy propagation of mode LP 01 and its parameters FWHM eff and MFD eff . Each splitter branch was placed at 0 and 1 cm from the mobile head of the BP109-IR and then the parameters were measured. Both measured splitters have the same split ratios, but their measured values are different, therefore it is technologically impossible to produce splitters with the same parameters, which implies that the effect of degradation mechanisms will be different.
