A Negative-Curvature Hollow-Core Fiber Structure With Double Trigonal-Symmetrical Anti-Resonant Elements

open access: yesIEEE Photonics Journal, 2022
We propose a novel negative-curvature hollow-core fiber structure with double trigonal-symmetrical anti-resonant elements implementing single-mode or polarization-maintaining transmission for high-power laser delivery in the 1 µm wavelength window.

Evaluating single-mode nonclassicality [PDF]

open access: yesPhysical Review A, 2020
Quantifying nonclassicality of a bosonic mode is an important but challenge task in quantum optics. Recently, the first nonclassicality measure based on the concept of operational resource theory has been proposed [Phys. Rev. Research 2, 023400 (2020)], which shows several crucial properties as a resource for quantum metrology.
