The most popular method for permanent connecting of optical fibers is thermal bonding with fusion or filament splicers. However, this method in some cases is not suitable, for example if the connected fibers are made of materials with different melting temperatures (i.e. silica and soft glass fibers) or in the case of microstructured optical fibers filled with materials which are highly sensitive to high temperature (i.e. organic materials such liquid crystals). In this work we will present some practical issues of an alternative method of permanent connecting various types of optical fibers by gluing with the use of photo-curable adhesives.
