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 ...

Birefringent optofluidic gratings
Optics Express, 2020 A set of parallel microfluidic channels behaving as a diffraction grating operating in the Raman-Nath regime has been fabricated and studied. The diffraction efficiency of such structure can be tuned by selecting a liquid with a particular refractive index and/or optical anisotropy.
