Birefringence index
WebMar 11, 2024 · Applications. Birefringence has several applications. It can be used to find defects in the manufacturing process, or identify weak spots in plastic structure manufactured via injection molding. It is also used extensively in optical communications to change linearly polarized light into circularly polarized one and vice versa. http://www.mt-berlin.com/frames_cryst/descriptions/birefringent.htm

WebTechniques are provided for radiation-induced birefringence in a Polarization-Maintaining Fiber (PMF). In one example, a fiber is obtained. At least one local volume of the fiber is irradiated to induce an end-to-end birefringence in the fiber. Based on the end-to-end birefringence induced in the fiber, a PMF is produced.
