Description

technical field

[0001] The invention relates to the field of optical fiber communication, in particular to a microstructure polarization maintaining optical fiber, the international patent classification number is intended to be Int.Cl 7 .C03B 37 / 00. Background technique

[0002] Polarization-maintaining fiber is an important class of fiber, which has important applications in many fields such as optical communication, optical signal detection and processing. It was mainly used for fiber optic sensing at first, and with the development of fiber optic communication technology, it has also been widely used in fiber amplifiers, fiber lasers, wavelength division multiplexing and polarization mode dispersion compensation. Polarization-maintaining fibers also play an important role in high-bit-rate optical communication systems because high-birefringence fibers can eliminate the effects of polarization mode dispersion.

[0003] In recent years, it has been proposed to use photon...
