Published in 2024 at "Scientific Reports"

DOI: 10.1038/s41598-024-69407-2

Abstract: We propose a novel miniaturized optical attenuator based on the evanescent-field coupling between two nanofibers. Benefiting from a wavelength-dependent waveguiding property of the coupled structure, a tunable attenuation with maximum extinction ratio of ~ 20… read more here.

Published in 2025 at "Entropy"

DOI: 10.3390/e27060631

Abstract: A homodyne detector, which is also a common element in current telecommunication, is a core component of continuous-variable quantum key distribution (CV-QKD) since it is considered the simplest setup for the distinguishing of coherent states… read more here.
