Birefringence – double refraction, uniaxial, biaxial crystals, induced ...
In optical fibers, birefringence can be caused by an elliptical shape of the fiber core, by other asymmetries of the fiber design (particularly for photonic crystal fibers), or by mechanical stress (e.g. caused by bending).
Another type of stress birefringence called temporal or transient stress birefringence is caused by stress resulting from thermal gradients occurring in application.
Induced Birefringence - an overview | ScienceDirect Topics
Stress-induced birefringence is a typical phenomenon inevitable in polymer optical components.
Thermal-stress-induced birefringence management of complex …
2022年10月31日 · This polarization change originates from stress induced birefringence caused by heat load occurring dominantly in the amplifier.
Stress-induced birefringence in large-mode-area micro …
We report on detailed numerical investigation of stress-induced birefringence in micro-structured solid-core optical fibers. The stress is induced either by external forces or stress applying parts inside the fiber.
Stress-Induced Birefringence | 25 | Polarized Light and Optical …
Stress induced birefringence is a widespread and often unavoidable problem in optical systems which frequently occurs in injection molded plastic optics due to molding processes, and in glass lenses as a result of poor opto-mechanical mounting techniques.
Long-Time Relaxation of Stress-Induced Birefringence of ...
2018年3月25日 · It was found that, after stress release, the SIB exhibited nonlinear long-time relaxation, which roughly converged within several hours, with the only time-invariant intrinsic birefringence remaining being due to OA.
Simple multi-wavelength imaging of birefringence:case study of silk
2018年12月5日 · In this study, we used a simple LC-cell (Fig. 1(a)), which has an electrically controlled birefringence (Fig. 1(b)), as a compensator for the determination of the birefringence of a single silk...
Laser-Inscribed Stress-Induced Birefringence of Sapphire
2019年10月3日 · Birefringence induced by stress and expanding beyond laser-structured regions is promising for polarization micro-optics, especially when the laser modified regions are not used for optical functions due to considerable light scattering losses.
Measurement of stress-induced birefringence in a thin-disk laser …
It is concluded that stress-induced birefringence should be taken into consideration when designing a thin-disk laser system. Stress-induced birefringence leads to losses in solid-state laser resonators and amplifiers with polarized output beams.
