| Abstract(in English) | A novel method for determining mode power distribution in a two mode fiber by measuring the near field pattern on the test fiber endface is developed. This method utilizes the different field symmetries of the fundamental and the second order modes. Coupling efficiencies from a quasi-gaussian beam to the fundamental and the second order modes in a two mode fiber were measured by the newly developed method for various offset launching conditions, and they were in good agreement with the theoretical ones. |
