Photonic lanterns are a kind of low loss optical waveguide device which interfaces single multimode waveguides and multiple waveguides that support fewer modes. This paper focused on the fabrication process and the testing requirement of the performance of photonic lanterns. A method for evaluating the performance of a photonic lantern device using digital holographic grating correlation filtering method was proposed. The principle of mode decomposition and the layout of the experimental device were introduced. The real-time measurement of the mode compositions of the 3×1 photonic lantern was carried out. The correlation coefficient was used to evaluate the accuracy of the model measurement. The results showed that the correlation degree of the method was more than 97 %, which could be used to accurately evaluate the quality of the photonic lantern device.
