Kerr-Nonlinearity-Induced Mode-Splitting in Optical Microresonators

Suppression of pulse splitting in two-core optical fibers with Kerr nonlinearity

Mode interaction in multi-mode optical fibers with Kerr effect

The coupled nonlinear Schrödinger equations (CNLS) which describe two linearly polarized modes interaction (with taken into account the polarization modes interaction) in the Kerr medium is derived. We take first two modes for cylindrical fiber which are also known as HE11 and TE01 modes which have different propagation constant. This approach bases on projection to orthogonal function basis (B...

Unified approach to mode splitting and scattering loss in high- Q whispering-gallery-mode microresonators

Current theoretical treatments of mode splitting and scattering loss resulting from subwavelength scatterers attached to the surface of high-quality-factor whispering-gallery-mode microresonators are not satisfactory. Different models proposed for distinct scatterer regimes cannot be reconciled. In addition, many experimental results are difficult to understand within the existing theoretical f...

Atomic coherence induced Kerr nonlinearity enhancement in Rb vapour

The Kerr nonlinear index of refraction for rubidium atoms is measured by using an optical ring cavity with and without electromagnetically induced transparency (EIT). Significant enhancement and inhibition of the Kerr nonlinear index is observed near resonance with EIT. The nonlinear index of refraction is measured as functions of probe and coupling frequency detunings, respectively, with and w...

Mode expansion modeling of rectangular integrated optical microresonators

Abstract: Two dielectric waveguides that are evanescently coupled to a square or rectangular region of increased refractive index can serve as a very compact integrated optical microresonator. We consider these devices in a spatial two-dimensional setting, where a rigorous mode expansion technique enables accurate and quite efficient numerical simulations of these configurations. The paper is c...
