Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Evaluation of the Scintillation Loss for Optical Communication Systems with Direct Detection
, 2006 In optical communications through the atmosphere, the evaluation of a link feasibility often requires the quantification of the scintillation penalty in terms of power loss. To find how much additional optical power is needed to reach the bit-error-rate (
