Hysteresis in the complex nonlinear refractive index of a homogeneous and isotropic medium
Igor Kuzmenko, Y. B. Band, Yshai Avishai +1
We calculate the permittivity, , for a medium with a quadratic electro-optic effect, modeling it as a Duffing oscillator. The nonlinear refractive index and…
Effective refractive index of a silicon dioxide with implanted Ag nanoparticles and Er ions
Igor Kuzmenko, Y. Avishai, Y. B. Band
We consider light propagation in a silicon dioxide substrate with implanted ions and silver nanoparticles that are randomly and homogeneously distributed in th…
Geometric Phases in Optics: Polarization of Light Propagating in Helical Optical Fibers
Y. B. Band, Igor Kuzmenko, Yshai Avishai
The geometric phase in optics (GPIO) is directly associated with the polarization of light. We investigate the physical principles underlying the occurrence of the GPIO for a singl…
Negative Refraction in isotropic achiral and chiral materials
Y. B. Band, Igor Kuzmenko, Marek Trippenbach
We show that negative refraction in materials can occur at frequencies where the real parts of the permittivity $\veps(Ï)$ and the permeability have different sign,…
