Polarization in photonic‐integrated circuits (PICs) is governed by transverse electric (TE) and magnetic (TM) polarizations due to the planar structure of the chips. Therefore, all states of polarization (SOPs) other than TE and TM, in particular c

Electromagnetic tensors

Autor: Stephan, Guy Michel

The electromagnetic potential A i is a quadrivector in Minkowski space-time x k and its gradient a i k is a tensor of rank two whose elements are the sixteen partial derivatives ∂A i /∂x k. We study in this article the properties of a family of t

Surface chemistry of perovskite nanoplatelets exhibiting circularly polarized luminescence

Autor: Austin Hubley, Amina Bensalah-Ledoux, Bruno Baguenard, Stephan Guy, Benjamin Abécassis, Benoit Mahler

Chiral halide perovskite nanocrystals have many applications in next-generation optoelectronic devices due to their interaction with circularly polarized light. Through the careful selection of chiral organic surface ligands, control over the circula

Theorie du potentiel, équations de Maxwell et force de Lorentz

Autor: Stephan, Guy Michel

We show that Maxwell equations and the Lorentz force can be expressed in terms of the spatial and temporal derivatives of the electromagnetic potential.
On montre que les équations de Maxwell et la force de Lorentz peuvent être exprimées en f
