Abstract

We propose a simple method for measuring the mode power of two-mode fiber based on the bending method. The mode power ratio is determined with better than 1 dB accuracy by undertaking three power measurements with different numbers of fiber bends. We also evaluate the estimation error of the proposed method and the required resolution of the measurement.
