Model for mirrorless optical multiple bistability due to increasing and decreasing absorption

Joseph W. Haus; C. C. Sung; Charles M. Bowden; J. M. Cookt

Heat conduction and propagation of the electromagnetic field as well as temperature-dependent absorption are considered in a model for mirrorless optical bistability. The effects of temperature and laser-frequency detuning are calculated and discussed. It is shown that the multiple bistability of output intensity as a function of input intensity can be induced and controlled by the temperature boundary conditions. It is emphasized that changes in these boundary conditions determine the details of the transmission characteristics.

Cooperative Transients In Inter-Atomic Correlation In The Presence Of An Externally Applied Coherent Field: Relation To Intrinsic Mirrorless Optical Bistability

Charles M. Bowden; C. C. Sung

Our model, presented earlier, which predicts the circumstances under which intrinsic mirrorless optical bistability (OB) can occur due to atomic pair correlation in a small volume, is outlined and the results presented. These results, which Predict a first-order phase transition in steady state for an externally-driven collection of a large number of atoms far removed from thermodynamic equilibriun, forms the motivation for a detailed microscopic examination of the dynamical behavior of atonic pair correlation in the presence of externally-applied coherent radiation. 4 model is presented and results are discussed for the transient dynamic evolution of two, two-level atoms separated from each other by a distance r in the presence of an externally-applied coherent radiation field. The results predict collective radiation reaction, frequency shifts, relaxation in terms of the atomic seoaration r (assumed much larger than single atom dimensions), the externally-applied field intensity and spacial uniformity of the field with respect to the inter-atomic volume.

Model of optical bistability in the quantum-well self-electro-optic-effect device

J. C. Englund; C. C. Sung; Y. Q. Li

Optical bistability of the multiple-quantum-well self-electro-optic-effect device is studied using a detailed model for a P–I–N photodiode under a constant voltage bias. By solving the Maxwell equations with the experimentally determined absorption function, bistability curves are obtained as functions of the incident frequency and of the bias potential. These results show good agreement with previously reported experimental data.

Models for Absorption-Induced Optical Bistability in CdS and Multiple Quantum Well GaAs

Joseph W. Haus; C. C. Sung; Y. C. Li; Charles M. Bowden; J. M. Cook

We have recently presented a theory for mirrorless optical bistability due to a coupling between the attenuation of the electromagnetic field and the temperature1. The parameters chosen in our work were appropriate for CdS platelets and we found multiple bistability of the output intensity as a function of the input intensity which was controlled by the temperature boundary conditions. The theory was qualitatively compared with low-temperature experimental results on CdS platelets2 and applications of these devices were considered for novel logic gates and multiplexing3.

Stationary properties of dispersive optical bistability in a dense exciton-biexciton system: copper chloride

C. M. Bowden; J. W. Haus; C. C. Sung; W. K. Chiu

A semiclassical exciton-biexciton model for CuCl is used to obtain the stationary solutions for optical bistability (o.b.) by numerical integration of the second-order Maxwell equation in the limit of large Fresnel numbers. The results obtained from the calculation, which we call exact (ex.), are compared with corresponding numerical results by using the slowly varying envelope approximation (s.v.e.a.) as well as corresponding analytical results obtained by using the mean-field approximation (m.f.a.). The results obtained with the s.v.e.a. are shown to be in close quantitative (within 5%) agreement with the ex. results for each point in the parameter space considered, whereas the m.f.a. gives reasonably good qualitative results only (more than 20% quantitative discrepancy with ex.). Furthermore, o.b. is predicted from these calculations for incident laser field detunings on either side of the two-photon biexciton resonance as well as in the neighbourhood of the resonance. The nonlinearity in the dielectric function that causes o.b. is seen to be very nearly of the Kerr medium type, and consequently, the two-photon biexciton resonance contributes only weakly to the o.b. characteristics.
