Abstract

With the growing interest in less-mode fibers in telecommunication and high-power lasers, fiber mode diagnostic techniques are gradually becoming one of the research hotspots in the field of lasers. In this paper, a four-channel off-axis holography is introduced to represent the polarization and the mode coefficients of LP modes in few-mode fiber simultaneously. A simulation study of Hi1060 fiber containing six linearly polarized modes at 632.8nm is carried out, and the results show that the errors of each mode coefficients is lower than 0.05, and the similarity of intensity before and after mode diagnostic is above 0.97.
