“…In the past decades, optical beam deflection has achieved a considerable attention. The deflection of light beam can be achieved by mechanical interaction [1], thermal gradient [2], acousto-optical interaction [3], electro-optic effect [4] and all-optical methods [5]. Optical methods have enjoyed much attention due to their high speed, efficiency and fast nonlinear response time.…”

We study the angular deflection of the circular polarized components of a linearly polarized probe field in a weakly birefringent atomic system in tripod configuration. A spatially inhomogeneous control field incident obliquely onto an atomic vapor cell facilitates a large angular divergence between circular components. We show that the angular resolution can be dynamically controlled by optimally choosing the angle of incidence and the transverse profile of the control beam. For instance, by employing a Laguerre-Gaussian profile of the control field, one can impart a large angular divergence to the circular components close to the entry face of the atomic vapor cell. We further demonstrate how such a medium causes the focusing and refocusing of the probe field, thereby acting as a lens with multiple foci. The absorption in the medium remains negligible at resonance due to electromagnetically induced transparency (EIT)

“…The guiding and steering of an optical beam is made possible by virtue of a refractive index of the medium. Several techniques such as mechanical [1,2], thermal [3], electrical [4], acousto-optical [5] and all optical [6][7][8][9] have been proposed to control the refractive index for beam deflection. However, all-optical methods have been paid much effort owing to many striking features such as high speed, efficiency, and quick nonlinear response time.…”

We propose an all-optical anti-waveguide mechanism for steering, splitting, and cloning of an optical beam beyond the diffraction-limit. We use a spatially inhomogeneous pump beam to create an anti-waveguide structure in a Doppler broadened N -type four-level Raman gain medium for a co-propagating weak probe beam. We show that a transverse modulated index of refraction and gain due to the spatially dependent pump beam hold the keys to steering, splitting and cloning of an optical beam. We have also shown that an additional control field permits the propagation of an optical beam through an otherwise gain medium without diffraction and instability. We further discuss how finesse of the cloned images can be increased by changing the detuning of the control field.

Image Scanning by Rotation of a Hologram

Abstract: Reconstructed image scanning can be provided by simple rotation of a hologram. Motion of the image is described as a function of the rotated angle. Application to the problem of beam forming and deflection is discussed.
