Background
Optical fiber communication is a communication mode that laser is used as an information carrier and optical fiber is used as a transmission medium, and the optical fiber is a main medium for broadband transmission of information at present. A single-mode optical fiber with a circularly symmetric structure theoretically has two orthogonal polarization modes that are independent and complementary to each other, and in general, the electric field of light propagating through the fiber can be considered as a linear superposition of these two special polarization modes. In fact, in single mode fibers, compensation of both polarization modes occurs due to defect factors such as symmetric transverse stress or eccentricity of the circular core. The two modes propagate at different phase rates and therefore have different propagation constants. The difference in the propagation constants becomes birefringence, and an increase in birefringence means an increase in the velocity difference between the two polarization modes.
