Corresponding relationship between characteristic birefringence, strain, and impurities in Zimbabwean mixed-habit diamonds revealed by mapping techniques [PDF]
European Journal of Mineralogy, 2022 Birefringence in diamond is an optical phenomenon related to strain and various defects in crystal lattices. Despite extensive investigations being done to characterize and quantify it, there is still controversy about its origin in diamond lattices ...

Birefringence for Elliptical-Core Fibers with Low Ellipticities
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2022 Model birefringence was measured for elliptical-core fibers with low ellipticities, note the birefringence depends strongly on the frequency, especially when fiber is being operated near the higher mode cutoff where ν for circular fiber of the single ...
