Propagation characteristics of guided modes on fiber-core spliced section and application to monomode fiber directional coupler
The first-order perturbation theory is used to analyse the propagation characteristics of guided modes on fiber-core spliced section. The results are applied to determine the theoretical coupling amount of monomode optical fiber directional coupler with strong transverse coupling by means of the mode excitation theory. Our theoretical results are in good agreement with the experimental measurements.
