Title
Topologické spin-fotonické lasery pro datové komunikace
Code
25-15775S
Summary
The need for increasing data transfer speed and security is triggering a persistent search for
ways to overcome the limitations of conventional intensity-modulated lasers. The recent
development of lasers driven by the spin current reveals a novel concept based on a
polarization-modulation approach with the potential to enhance security and boost the capacity
of optical communication by more than an order of magnitude. The project aims at the deep
exploration of (i) the ultrafast dynamics of spin-polarized vertical-cavity surface-emitting lasers
(spin-VCSELs) with intra-cavity photonic nanostructures promising the modulation exceeding
terahertz frequency and (ii) non-classical photon statistic approaches for enhanced safety
against eavesdropping. Theoretical and numerical modeling, design, preparation, and
characterization of the novel spin-VCSEL devices require the complementary theoretical and
experimental expertise of three partner laboratories from the Technical University of Ostrava,
Palacky University, and Czech Technical University in advanced classical and quantum optics.
Project Aims in
English Theoretical design and experimental realization of two-mode spin-laser using intracavity
anisotropic nanostructure; exploration of quantum-optical and non-classical properties of spin-
VCSEL emission; experimental proof-of concept for ultrafast dynamics and polarization
modulation of spin-VCSEL.
