Web1 de jan. de 2024 · A novel Zeonex based porous fibre is proposed for biomedical imaging and polarisation preserving applications of terahertz waves. The standard finite element method is used to simulate the propagation characteristics of the fibre that shows high numerical aperture of 0.48, high birefringence of 0.039 and a flattened dispersion of … WebBirefringence is a measure of a gem's double refraction. It serves as one of the principal ways gemologists can identify gems. Natural zircon (not to be confused with cubic zirconia) has been used to create convincing diamond imitations. However, this gem is doubly refractive and has a high birefringence.
WebA retrospective study recently showed that oocytes presenting with a high birefringence of the inner zona layer were more often associated with conception cycles. To further investigate these findings, a prospective study was conducted between September 2005 and September 2006 including intracytoplasmic sperm injection (ICSI) cycles presenting … Web1 de set. de 2024 · In this Letter, for the first time, high birefringence in a VCSEL is induced with an etched surface grating. Previous work. As mentioned before, a high amount of birefringence has to be implemented in a VCSEL to obtain extremely fast polarisation dynamics and wide modulation bandwidth. Initially, we used a simple bending mechanism.

WebAbstract. Coiling a single-mode fiber of radius r under tension onto a cylinder of radius R produces a linear birefringence of βtc ≃ 28 × 10 7 ∊2r / R deg/m in the fiber at λ = 0.63 μ m, where ∊z is the relative fiber elongation. Polarization beat lengths down to 2.5 cm have been realized this way, providing excellent polarization ...
