DETERMINATION OF OPTICAL LOSSES AT FIBERS JOINING WITH DIFFERENT MODEFIELD DIAMETER
Read the full article
For optical losses reducing at fiber optic systems creation the angular distribution of the output radiation of birefringent optical fibers with elliptical stress cladding with 4, 12, 16 and 18 mol. % GeO2 is measured. Obtained data make it possible to predict losses at joining of optical fibers with elliptical stress cladding and different concentrations of GeO2 with each other, as well as standard telecom fibers, such as SMF-28, other birefringent optical fibers and integrated optics components.
