Strong circular dichroism in twisted single-ring hollow-core photonic crystal fiber
P. Roth, Y. Chen, M. C. Günendi +6
We report a series of experimental, analytical and numerical studies demonstrating strong circular dichroism in helically twisted hollow-core single-ring photonic crystal fiber (SR…
