The theoretical principle and experimental procedure of a new method of measuring the coupling length of a twin-core fiber are presented. This method is simple, nondestructive, and gives direct results without extensive data processing. It is based on the elasto-optic technique and had a very good spatial resolution so that coupling lengths of the order of… CONTINUE READING
