摘　　要：The lightwave field possesses several dimensional properties,including amplitude,spectrum,phase,and polarization.Multidimensional measurements of lightwaves have diverse applications ranging from remote sensing to analytical chemistry.However,achieving high-resolution simultaneous multi-dimensional measurement of lightwaves remains challenging.In this work,we demonstrate an all-fiber spectropolarimeter based on a speckle pattern obtained from the end of a multi-mode fiber.The proposed system simultaneously achieves a spectral resolution of 100 pm and a polarization resolution of 0.001437.The polarization measurement errors for three Stokes parameters are 3.37%,1.01%,and 0.84%,respectively,with a mean squared error of 5.3×10^(-5).This work provides novel potential for high-resolution and accurate multi-dimensional lightwave field measurements.
