Abstract

The finite-difference time-domain (FDTD) method is applied to investigate the characteristics of nonlinear Fabry-Perot (FP) resonators in optical waveguide geometries. Our treatment, which is the extension of Tran's method developed to analyse the characteristics of nonlinear photonic crystals, correctly reproduces analytical results on optical bistabilities of the FP resonator provided by Chen and Mills in 1987. It is found that the minimum power required for optical bistabilities is significantry decreased by adopting the optical waveguide geometry, compared with the case of Chen and Mills, i.e., a conventional nonlinear FP interferometer.

Modeling of nonlinear bistability with the FDTD method

T. Hruskovec, Zhizhang David Chen

Bistability due to the nonlinearity of an optical material has been studied recently and investigated for its potential high-speed all-optical signal-processing applications. As a result, accurate modeling techniques are required for design purposes. In this paper, the finite-difference time-domain (FDTD) method is applied to the modeling of optical bistability caused by the saturable Kerr effect of a GaAs–GaAlAs MQW-like material. A recursive finite-difference formulation for the saturable Kerr properties of the material is derived, and a physically realizable Fabry–Perot etalon is simulated. The numerical results demonstrate the effectiveness of the FDTD method for bistability modeling, and thus provide the foundations for further work and simulation of more complicated and realistic bistable structures. ©1999 John Wiley & Sons, Inc.

Optical bistability in an all-optical fiber nonlinear fabry-perot resonator with linear absorption

Shenping Li, K.T. Chan

An all-optical fiber nonlinear Fabry-Perot resonator is proposed. The steady-state model for describing this resonator is developed. The transmission and refection bistabilities are shown numerically. Our results show that the bistability in this system is similar to that in a normal nonlinear Fabry-Perot etalon, except that the characteristics of the bistability can be changed not only by the cavity length but also by the phase shifts of the fiber loop mirrors.

Nonlinear Fabry-Perot resonator with a silicon photonic crystal waveguide

Kazuhiro Ikeda, Yeshaiahu Fainman

We derive an equation that describes the nonlinear operation of a Fabry-Perot resonator with a large group index waveguide. Specifically, a silicon photonic crystal microcavity with two-photon-excited free carrier nonlinearity and Kerr nonlinearity is assumed. The equation clearly explains the bistability of the device and the reduction of the required pump energy for a specific nonlinear phase shift at an appropriate phase detuning from the resonance. We present a simple procedure to predict the required optical pump energy for the modulation and the resulting modulation depth by use of the equation and the device parameters.

Dynamics and Transverse Effects in Nonlinear Planar Resonators: A Unified Modal Theory

Marc Haelterman, Guy Vitrant

In a recent paper, we proposed a new theoretical model of nonlinear optical cavities1. Our theory, which is valid for both nonlinear (NL) waveguide couplers and NL Fabry-Pérot (FP) with arbitrary angle of incidence, constitutes a unified theory of nonlinear planar resonators. The main advantage of the model is that it greatly simplifies the numerical study of transverse effects in NL resonators and provides a deep understanding of physical phenomena related to Optical Bistability (OB) in such devices. In particular it allowed us to analyse the role of diffraction and the influence of the incident angle on the steady-state NLFP response1,2.
