High birefringence

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. WebWe report the first high-birefringence hollow-core anti-resonant fiber with a pseudoCv symmetry. The resulted fiber shows a phase birefringence, polarization etfinction ratio, and loss of 0.9 X10-4, 25 dB, and 250 dB/km, respectively, at 1550 nm.
