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, $I^µ (I ¨ )$ , for a medium with a quadratic electro-optic effect, modeling it as a Duffing oscillator. The nonlinear refractive index $n (I ¨ , E (I ¨ ))$ and…

Effective refractive index of a silicon dioxide with implanted Ag nanoparticles and Er $^{3 +}$ ions

Igor Kuzmenko, Y. Avishai, Y. B. Band

We consider light propagation in a silicon dioxide substrate with implanted $Er^{3 +}$ 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…
