New laser-based bistability system for optical computing applications

Abstract

We have studied analytically the theoretical behavior of a Fabry-Perot cavity using a birefringent non-linear material in a polarizer-sample-analyzer system. The working parameter of our device is the direction of polarization of the incident light. Principal results are presented.

Polarization induced switching and polarization bistability in non-linear Fabry-Perot resonators

Hugo Thienpont A, Jan Danckaert, Irina P. Veretennicoff

The author aims at merging polarization optics and non-linear optics for non-linear Fabry-Perot cavities. The in-depth study shows, both from a stationary and a dynamical approach, that polarization modulation leads among others to a novel switching mechanism. Furthermore, in well defined circumstances, using e.g., anisotropic cavity materials, polarization optical bistability can occur. Aspects of the dynamics of these processes are highlighted and applications are suggested.

Polarization-induced switching and polarization bistability in nonlinear planar resonators with diffusive nonlinearity

Jan Danckaert, Hugo Thienpont A, Irina P. Veretennicoff

To merge the fields of polarization and nonlinear optics opens wide perspectives. The present work aims at investigating some of them. It is shown, on one hand, that if a nonlinear Fabry- Perot resonator filled with an optically isotropic material is addressed by an obliquely incident beam, the transmitted irradiance can switch from an up to a down state (or the reverse) if its polarization is properly modulated. If on the other hand the nonlinear cavity is filled with a linearly birefringent material, polarization optical bistability can occur, even at normal incidence. This polarization bistability can arise both by modulating the incident irradiance and by modulating the incident polarization. Optical bistability of the transmitted irradiance can also be induced by the modulation of the polarization of the incident beam. All these features provide new tools for parallel digital optical information processing.

Coupling of orthogonal polarizations in a nonlinear, birefringent cavity

K. C. Ho, Guy Indebetouw

Polarization bistability has been proposed as having a number of advantages over conventional schemes.1 We have investigated polarization switching in a Fabry-Perot cavity filled with an aligned nematic. In this nonlinear, birefringent cavity, the transmittance for each polarization is a single valued function of the irradiance inside the cavity. This couples the two polarizations so that, unless sufficiently separated spatially, they switch simultaneously. Although limiting the range of possible applications, this coupling may be used to advantage to implement some optical latches.

Polarization-based all-optical bistable element

Theoretical studies are given for a nonlinear Fabry-Perot resonator filled with a birefringent medium or a gyrotropic medium. The results mapped onto Poincare's spheres show the changes of the output polarization states due to the changing input intensities.

Polarization switching versus optical bistability: Experimental observations for a Jlower=1 to Jupper=0 transition in a Fabry-Perot cavity

Christian G. Parigger, Peter Hannaford, Weston J. Sandle

Experiments on the steady-state, nonlinear behavior of the $^{7}\mathrm{F}_{1}$${\mathrm{\ensuremath{-}}}^{7}$${\mathrm{F}}_{0}^{\mathrm{o}}$ 570.68-nm transition of atomic samarium in a laser-driven, near-concentric Fabry-Perot cavity are reported. For zero applied magnetic field, only simple optical bistability, symmetric in both ${\ensuremath{\sigma}}^{+}$ and ${\ensuremath{\sigma}}^{\mathrm{\ensuremath{-}}}$ transmitted polarizations, is observed for a linearly polarized excitation beam. However, for a magnetic field applied parallel to the propagation direction, polarization-sensitive switching appears, with lowest power threshold near the edge of the Doppler-broadened region. Subsidiary measurements of atomic parameters are also given to enable the transition to be experimentally well characterized.
