Photon-photon interaction in a photon gas [PDF]

open access: yesEurophysics Letters (EPL), 2000
Using the effective Lagrangian for the low energy photon-photon interaction the lowest order photon self energy at finite temperature and in non-equilibrium is calculated within the real time formalism. The Debye mass, the dispersion relation, the dielectric tensor, and the velocity of light following from the photon self energy are discussed.

Non-invasive monitoring and control in silicon photonics by CMOS integrated electronics [PDF]

open access: yes, 2014
As photonics breaks away from today's device level toward large scale of integration and complex systems-on-a-chip, concepts like monitoring, control and stabilization of photonic integrated circuits emerge as new paradigms.

Photon–photon scattering: a tutorial [PDF]

open access: yesCanadian Journal of Physics, 2012
Long-established results for low-energy photon–photon scattering, γγ → γγ, have recently been questioned. We analyze that claim and demonstrate that it is inconsistent with experience. We demonstrate that the mistake originates from an erroneous manipulation of divergent integrals and discuss the connection with another recent claim about the Higgs ...

Influence of the Surface Roughness of a Silicon Disk Resonator on Its Q-Factor

open access: yesPhotonics, 2021
This article presents a silicon disk resonator of the whispering-gallery-mode (WGM) type. The calculated Q-factor of the silicon WGM resonator was 107. Two methods of studying the surface roughness of a silicon WGM resonator with a nonlinear profile by ...

HIGH ENERGY PHOTON-PHOTON AND ELECTRON-PHOTON COLLISIONS [PDF]

open access: yesInternational Journal of Modern Physics A, 1998
The advent of a next linear e±e- collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ*γ*→X in the region dominated by BFKL hard Pomeron exchange and report the ...
