Beam Shaping and Control with Nonlinear Optics

We demonstrate the feasibility of strong (up to atomic fields) and super-short (fewor even sub-femtosecond) sub-cycle (non-oscillating) electromagnetic solitons -EM bubbles (EMBs) in a gas of two-level atoms, as well as EMBs and pre-ionization shock waves in classically nonlinear atoms. We show that EMBs can be generated by existing sources of radiation, including sub-picosecond half-cycle puls...

Fully controllable adiabatic geometric phase in nonlinear optics.

We propose and analyze a new way for obtaining an adiabatic geometric phase for light, via the sum-frequency-generation nonlinear process. The state of light is represented by the complex amplitudes at two different optical frequencies, coupled by the second order nonlinearity of the medium. The dynamics of this system is then shown to be equivalent to that of a spin-1/2 particle in a magnetic ...

Nonlinear optics with local phasematching by quantum-based meta-material

We propose a novel artificial medium, which locally provides both the optical nonlinearity and simultaneously the phasematching for the macroscopic build-up of the generated field. This is achieved by a special assembly of semiconductor quantum wells, which by careful design are both nonlinear and appropriately dispersive. A critical point for a practical realization of this meta-material is it...
