Generation of three wide frequency bands within a single white-light cavity

Anas Othman, David O. Yevick, M. Al-Amri

We theoretically investigate the double-$\mathrm{\ensuremath{\Lambda}}$ scheme inside a Fabry-P\'erot cavity employing a weak probe beam and two strong driving fields together with an incoherent pumping mechanism. By generating analytical expressions for the susceptibility and applying the white-light cavity conditions, we devise a procedure that reaches the white-light condition at a smaller gas density than the values typically cited in similar previous studies. Further, when the intensities of the two driving fields are equal, a single giant white band is obtained, while for unequal driving fields three white bands can be present in the cavity. Two additional techniques are then advanced for generating three white bands and a method is described for displacing the center frequency of the bands. Finally, some potential applications are suggested.

Control of Light-Matter Interactions in Classical and Quantum Optics

Anas Othman

In this thesis, we examined a series of techniques for controlling the interaction of light with matter that could be employed to optimize or to control physical phenomena in various potential applications. Some of these schemes are described with classical electrodynamic theory while others require a semi-classical or full quantum framework. \nIn Ch.(2), we study numerically two implementations of stretchable photonic crystals (SPCs) embedded in elastic polymers. Our analysis, which classifies the bandgaps in terms of two simply determined parameters, indicates that such structures exhibit bandgaps that can be readily adjusted by straining the polymer. \nIn Ch.(3), we considered a five-level atomic system in a dense gas interacting with two low-intensity fields. By examining the influence of different parameters on the refraction index we found that by adjusting the ratio of the two magnetic amplitudes associated with the fields the effects of atomic coherence can be simply controlled. As well, a negative index of refraction can be achieved and controlled over a wide wavelength range with minimal absorption. \nIn Ch.(4), we theoretically investigated the double Lambda scheme inside a Fabry-Perot cavity. By introducing a weak probe beam and two strong driving fields and employing an incoherent pumping mechanism we found that when the intensity of the two driving fields are equal, a single giant white band was generated. However, when they are not equal, three white bands can be present in one cavity. This procedure can also be employed to displace the center frequency of the white band. \nIn Ch.(5), we studied the interaction of a N-type four-level atom with a single field in the presence of an intensity-dependent coupling in a nonlinear Kerr medium. The exact analytic solution is obtained in the case that the atom and electromagnetic field are initially in a higher excited state and a coherent state, respectively. It is then demonstrated that nonclassical properties such as the degree of entanglement stabilization, Kerr medium nonclassical control, and squeezed light can be more efficiently realized and controlled within this four-level framework than in many competing procedures. \nFinally, in Ch.(6), we theoretically studied the superposition of two nearly identical coherent states. This ``near coherent'' state exhibits numerous nonclassical properties such as sub-Poissonian statistics, squeezing for certain relative phases of the superposition and a partially negative Wigner function.

Wide-band optical switch via white light cavity

Jingping Xu, M. Al-Amri, Yaping Yang +2 more

We propose a device whose reflectivity can be controlled optically over a wide frequency band. To this objective, we propose a Fabry-P\'erot cavity filled with a three-level atomic gas such that the effective susceptibility can be adjusted through incoherent pump and coherent driving fields. Adopting the concepts of electromagnetic-induced transparency and the white light cavity, we can control the susceptibility to break or satisfy the resonance condition over a wide frequency range, resulting in a wide-band optical switch. In addition to numerical calculation, we first give the analytical parameters, such as pump rate, and the Rabi frequency of the driven field, required for white light cavity in this paper. Using such a cavity as a wall of another cavity, we can, optically, realize a wide-band $Q$-switched cavity. Such a device can also be used as a new type of optical switch for quantum information.
