A bending-resistant low-crosstalk photonic orbital angular momentum (OAM) optical fiber waveguide. An optical fiber sequentially comprises, from the center to the outside, a first core layer (), a second core layer (), a first cladding layer (), a second cladding layer (), and a third cladding layer (), wherein the third cladding layer () is the thickest, the first core layer () is the second thickest, and the first cladding layer () is the thinnest; the refractive index of the first cladding layer () is the lowest, the refractive index of the second cladding layer () is the second lowest, and the refractive index of the second core layer () is the highest. The waveguide structure can effectively regulate the output of different OAM modes, and an effective refractive index difference between modes is greater than 2×10, the modes are easy to separate, and multiplexing and demultiplexing are facilitated.
