Femtosecond tunable solitons up to 4.8  µm using soliton self-frequency shift in an InF3 fiber

open access: yesScientific Reports, 2022
A tunable ultrashort soliton pulse source reaching up to 4.8 µm is demonstrated based on a 2.8 µm femtosecond fiber laser coupled to a zirconium fluoride fiber amplifier followed by a small core indium fluoride fiber.

Quantum electrodynamics in modern optics and photonics: tutorial

open access: yesJournal of the Optical Society of America B, 2020
One of the key frameworks for developing the theory of light–matter interactions in modern optics and photonics is quantum electrodynamics (QED). Contrasting with semiclassical theory, which depicts electromagnetic radiation as a classical wave, QED ...

Antireflection of optical anisotropic dielectric metasurfaces

open access: yesScientific Reports, 2023
We propose a hetero-nano-fin structure to further improve the efficiency of Pancharatnam–Berry phase metasurfaces. Two hetero-nano-fin types, MgF2/GaN and MgF2/Nb2O5, were investigated.
