摘要：
An all-fiber Sagnac interferometer using a birefringent fiber loop is used to determine the coupling coefficients of a fiber directional coupler. These coefficients are estimated by identifying the minimum value of the normalized transmittance of the filtered spectrum through the all-fiber Sagnac interferometer with respect of a simple appropriate model.
