We consider a nonlinear microcavity separating a waveguide channel into two parts so that the coupling between them is possible only due to the resonant properties of the microcavity. We provide a rigorous derivation of the equations used in the phenomenological coupled-mode theory for such systems. This allows us to find the explicit formulas for all fitting parameters such as decay rates, coupling coefficients, and characteristic intensities in terms of the mode profiles. The advantages of…

Coupled Whispering Gallery Modes under Kerr-Nonlinearity

The effect of Kerr-nonlinearity on coupled whispering gallery modes is studied. As a model system, we choose an add-drop filter, which comprises a circular microcavity and two side-coupled wave

Interaction between optical fields and their conjugates in nonlinear media.

A conceptually new model is introduced, based on the envelope of the analytic signal, that takes into account the full spectral dynamics of all frequency components, is prone to analytical treatment and retains the simulation efficiency of the nonlinear Schrödinger equation.



Nonreciprocal switching thresholds in coupled nonlinear microcavities.

A concept for the design of nonlinear optical diodes is proposed that uses the multistability of coupled nonlinear microcavities and the dependence of switching thresholds on the direction of incidence to describe the dynamical properties of such systems.

Temporal coupled-mode theory for the Fano resonance in optical resonators.

A theory of the Fano resonance for optical resonators, based on a temporal coupled-mode formalism, is presented and it is shown that the coupling constants in such a theory are strongly constrained by energy-conservation and time-reversal symmetry considerations.

Switching in coupled nonlinear photonic-crystal resonators

Using coupled-mode theory we examine the linear and Kerr nonlinear behavior of multiple consecutive photonic-crystal switches. Two types of resonators are considered, those with the cavity inside and

Temporal coupled-mode theory and the presence of non-orthogonal modes in lossless multimode cavities

We develop a general temporal coupled-mode theory for multimode optical resonators. This theory incorporates a formal description of a direct transmission pathway, and is therefore capable of

Self-pulsing and chaos in short chains of coupled nonlinear microcavities

We examine time-domain instabilities in short chains of coupled Kerr-nonlinear resonators. We show that a large parameter region of self-pulsing or chaotic behavior can be realized. We give a

In this paper, we review various numerical methods currently used to model nonlinear optical processes in nanophotonics. Among the different theoretical frameworks that have been used to study

For frequencies close to the edge of a stop gap of the structure, for rather low power, the system may switch from a state where the transmissivity is unity to a state Where it is exponentially small, and the theory is applied to finite superlattices.
