Tunable nanophotonics enabled by chalcogenide phase-change materials [PDF]

open access: yes, 2020
Nanophotonics has garnered intensive attention due to its unique capabilities in molding the flow of light in the subwavelength regime. Metasurfaces (MSs) and photonic integrated circuits (PICs) enable the realization of mass-producible, cost-effective ...

Emulating the local Kuramoto model with an injection-locked photonic crystal laser array

open access: yesScientific Reports, 2021
The Kuramoto model is a mathematical model for describing the collective synchronization phenomena of coupled oscillators. We theoretically demonstrate that an array of coupled photonic crystal lasers emulates the Kuramoto model with non-delayed nearest ...

Asymmetric transmission in nanophotonics

open access: yesNanophotonics, 2023
In a reciprocal medium, transmission of electromagnetic (EM) waves is symmetric along opposite directions which restrict design and implementation of various systems in optics and photonics.

Nanophotonics for pair production

open access: yesNature Communications, 2023
AbstractThe transformation of electromagnetic energy into matter represents a fascinating prediction of relativistic quantum electrodynamics that is paradigmatically exemplified by the creation of electron-positron pairs out of light. However, this phenomenon has a very low probability, so positron sources rely instead on beta decay, which demands ...

Ultrasonic signal detection based on Fabry–Perot cavity sensor

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2021
Acoustic/ultrasonic sensors are devices that can convert mechanical energy into electrical signals. The Fabry–Perot cavity is processed on the end face of the double-clad fiber by a two-photon three-dimensional lithography machine.

Lipid droplets as endogenous intracellular microlenses

open access: yesLight: Science & Applications, 2021
Using a single biological element as a photonic component with well-defined features has become a new intriguing paradigm in biophotonics. Here we show that endogenous lipid droplets in the mature adipose cells can behave as fully biocompatible ...
