Analysis of Quantum-Dot Spin-VCSELs

open access: yesIEEE Photonics Journal, 2012
The derivation of a set of rate equations (REs) to describe optically pumped quantum-dot (QD) spin-injected vertical-cavity surface-emitting lasers (VCSELs) is presented based on a modified version of the spin-flip model. The approach includes capture of

Evanescent wave induced polarization-insensitive self-organization of stratified single-negative materials

open access: yesNew Journal of Physics, 2021
Optical fields can induce optical forces between macroscopic objects, giving rise to different structures. Through rigorous calculation, we show that a collection of single negative slabs which possesses either negative permittivity or negative ...

Highly efficient vectorial field manipulation using a transmitted tri-layer metasurface in the terahertz band

open access: yesOpto-Electronic Advances, 2023
Polarization is a basic characteristic of electromagnetic waves that conveys much optical information owing to its many states. The polarization state is manipulated and controlled for optical information security, optical encryption, and optical ...
