Self-imaging in square fiber for CBC application

An all-fiber system based on the principle of optical waveguide self-imaging for coherent beam combination (CBC) system is designed. A square fiber is used as the beam combination device for all-fiber CBC system. The self-imaging characteristics of the square fiber are studied. The self-imaging effect of the square fiber is verified by theoretical simulation and experiment. The square fiber has good self-imaging characteristics and is suitable for CBC using its self-imaging characteristics.
