The application and future development direction of polarization maintaining fiber
Polarization-maintaining fibers will have a large market demand in the next few years. With the rapid development of new technologies in the world and the continuous development of new products, polarization-maintaining fibers will develop in the following directions:
(1) Using the new technology of photonic crystal fiber to manufacture new high-performance polarization-maintaining fiber;
(2) Develop temperature-adaptive polarization-maintaining fibers to meet the requirements of aerospace and other fields;
(3) Developed various rare earth-doped polarization-maintaining fibers to meet the needs of optical amplifiers and other device applications;
(4) Develop fluoride polarization-maintaining fibers to promote the development of fiber optical interference technology in the field of infrared astronomy technology;
(5) Low-attenuation polarization-maintaining fiber: With the continuous improvement of single-mode fiber technology, loss, material dispersion and waveguide dispersion are no longer the main factors affecting fiber communication, and the polarization mode dispersion (PMD) of single-mode fiber has gradually become a limitation. The most serious bottleneck of optical fiber communication quality is particularly prominent in high-speed optical fiber communication systems of 10 Gbit/s and above.
(6) Using the Kerr effect and Faraday rotation effect to fabricate polarized light devices.
In addition, depending on the fiber head, there are: C-Lens. G-Lens. Green lens
