Physical Review A

Strong parametric amplification by spatial soliton-induced cloning of transverse beam profiles in an all-optical antiwaveguide

Abstract

Spatial soliton-induced cloning, which achieves and maintains perfect spatial overlap of interacting beams, is proposed as a tool for amplification of nonlinear optical effects on propagation. This is illustrated by the enhancement of the parametric amplification, obtained through pump-induced cloning of the transverse profiles of the copropagating probe and generated four-wave mixing beams, in an all-optical antiwaveguiding configuration.

Steering, splitting, and cloning of an optical beam in a coherently driven Raman gain system

Onkar N. Verma, Tarak Nath Dey

We propose an all-optical antiwaveguide mechanism for steering, splitting, and cloning of an optical beam without diffraction. We use a spatially inhomogeneous pump beam to create an antiwaveguide structure in a Doppler broadened $\mathcal{N}$-type four-level Raman gain medium for a copropagating 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. We arrive at similar results by using homogeneously broadened gain media at higher density.

Phase control reduction of four-wave mixing in induced waveguiding scheme

D. Bortman-Arbiv, A. D. Wilson‐Gordon, Harry Friedmann

Summary form only given. We investigate the waveguiding induced in a weak probe propagating in a medium of two-level atoms driven by a copropagating, intense, strongly detuned pump. We show that when the transverse profile of the pump exhibits solitonlike oscillations, similar oscillations can be induced in the transverse profile of the probe. The pump acts as a spatial soliton in the sense that its transverse intensity profile displays oscillating spatial behavior due to the interplay of self-focusing and diffraction. This work suggests that the importance of four-wave mixing in modifying induced waveguiding should be considered in other waveguiding schemes. The potential of phase control in manipulating the properties of propagating laser light in a sophisticated way is emphasized.

Effect of four-wave mixing on induced waveguiding

D. Bortman-Arbiv, A. D. Wilson‐Gordon, Harry Friedmann

We study the waveguiding induced in a weak probe propagating in a medium of two-level atoms driven by a copropagating strong pump. We show that when the transverse profile of the pump exhibits solitonlike oscillations, similar oscillations can be induced in the transverse profile of the probe. When the probe waist size is initially narrower than that of the pump, the probe adjusts its width after a short propagation distance, to that of the pump. We show that the effect of the weak beam, which is created during propagation by four-wave mixing, on the waveguiding of the probe, becomes important when the medium is optically thick. This suggests that the importance of four-wave mixing in modifying induced waveguiding should be considered in other waveguiding schemes.

Beam steering using optical parametric amplification in Kerr medium: a space-time analogy of parametric slow-light

Gil Fanjoux, Éric Lantz, J. Michaud +1 more

In a way analogous to a light pulse that can be optically delayed via slow light propagation in Kerr-type nonlinear media, we theoretically demonstrate that beam steering and spatial walk-off compensation can be achieved in noncollinear optical parametric amplification. We identify this effect as a result of the quadratic phase shift induced by parametric amplification that leads to the cancellation of the spatial walk-off and collinear propagation of all beams though they have different wavevectors. Experimental evidence is reported of a soliton array steering in a Kerr slab waveguide.

Induced optical spatial solitons

D. Bortman-Arbiv, A. D. Wilson‐Gordon, Harry Friedmann

We show that under suitable conditions, a weak nondegenerate probe may become spatially confined in a Doppler-broadened medium composed of two-level atoms due to the effect of a strong resonant copropagating pump beam. The induced spatial solitons result from the interplay of diffraction and induced focusing of the probe. Realistic conditions that include effects of probe absorption and pump reshaping on propagation are examined. In order to avoid absorption of the near-resonant probe, which would make the strong induced focusing unobservable, the unique properties of the dead zone are exploited.

We propose an all-optical antiwaveguide mechanism for steering, splitting, and cloning of an optical beam without diffraction. We use a spatially inhomogeneous pump beam to create an antiwaveguide structure in a Doppler broadened N\mathcal{N}N-type four-level Raman gain medium for a copropagating 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.
