Modeling of optical bistability in reflection in GaAs/AlGaAs Fabry-Perot etalons including diffraction, carrier, and heat diffusion

Abstract

There is an increasing interest in all-epitaxial Fabry-Perot etalons for optical bistability1,2 and optical logic gates.3 To model these devices theoretically, the wave equation, carrier diffusion equation, and heat conduction equation must be solved self-consistently for the layered structure. To investigate the effects of small spot sizes, the wave equation must include diffraction, whereas for the heat conduction equation both longitudinal (perpendicular to the layers) as well as transverse (parallel to the layers) heat conduction must be taken into account.

Model for optical bistability in GaAs/AlGaAs Fabry–Perot étalons including diffraction, carrier diffusion, and heat conduction

Ulf Olin

A new model for optical bistability in layered semiconductor Fabry–Perot étalons is presented. The model accounts for diffraction, carrier diffusion, and thermal conduction. Assuming that the spot size and the thickness of the nonlinear layer are smaller than the diffusion length of the carriers, a simplified model is derived that has been used to design bistable AlGaAs étalons with improved thermal properties.

Theory for the temperature rise in optically bistable GaAs/AlGaAs étalons including diffraction, heat conduction, and carrier diffusion

Ulf Olin, Olof Sahlén

We report on a realistic model for optically bistable GaAs/AlGaAs Fabry-Perot étalons. The model incorporates diffraction, carrier diffusion, and heat conduction, taking all the layers of the structure into account. For the optical nonlinearity the carrier density and temperature-dependent plasma theory is used. Devices with less than a 1-K temperature rise should be possible to design.

Effects of diffraction and diffusion in dispersive optical bistability in Fabry–Perot étalons

Ulf Olin

Transverse effects in optical bistability, when both diffraction and diffusion are taken into account, have been studied. A numerical method is presented, as well as results for dispersive optical bistability in Fabry–Perot resonators for different diffusion lengths. It is shown that for small spot sizes, diffraction considerably influences the transmission characteristics and hysteresis disappears when diffusion is present.

Optical bistability in semiconductor periodic structures

Jian‐Jun He, Michael Čada

A theoretical demonstration of optical bistability in periodic layered media, particularly in long-period GaAs/AlAs superlattices is presented. The proposed structure consists of a periodic multilayer system, as opposed to previously demonstrated nonlinear bistable devices which employed Fabry-Perot etalons. The optical resonance effect which is essential for bistable devices is, in this case, induced by a refractive index modulation. The nonlinear active medium is distributed in the whole structure rather than placed between the two mirrors of a Fabry-Perot cavity. It is shown by a complete calculation of wave propagation in the periodic nonlinear medium that a multiple valued feature appears in the structure's nonlinear reflectivity spectrum. The input/output characteristics of the structure exhibit bistable hysteresis similar to that of a nonlinear Fabry-Perot etalon.>

Transverse effects in optical bistability with the nonlinear Fabry–Pérot étalon: A new theoretical approach

Marc Haelterman, Michael D. Tolley, Guy Vitrant

On the basis of a plane-wave analysis we develop an original one-dimensional model for the nonlinear Fabry–Pérot étalon. This model facilitates numerical analysis and physical interpretations. We discuss the role of diffraction and the influence of the incident angle on bistability. A preliminary numerical study of the model is proposed.

Optical bistability and gating in metalorganic vapor phase epitaxy grown GaAs étalons operating in reflection

Olof Sahlén, Ulf Olin, Eric Masseboeuf +2 more

Nonlinear Fabry–Perot étalons of GaAs have been fabricated with metalorganic vapor phase epitaxy technology. The étalons operate in reflection mode, and have an epitaxially grown, rear dielectric mirror consisting of a stack of alternating AlAs/GaAlAs layers. Optical logic functions using a HeNe laser and optical bistability at room temperature are reported. Low switching powers and improved étalon uniformity are obtained.
