Controllable Raman-like nonlinearities from non-stationary cascaded quadratic processes
F. Ö. Ilday, K. Beckwitt, Y. -F. Chen +2
We show that useful non-instantaneous nonlinear phase shifts can be obtained from cascaded quadratic processes in the presence of group velocity mismatch. The two-field nature of t…
A new chiral electro-optic effect: Sum-frequency generation from optically active liquids in the presence of a dc electric field
P. Fischer, K. Beckwitt, A. D. Buckingham +2
We report the observation of sum-frequency signals that depend linearly on an applied electrostatic field and that change sign with the handedness of an optically active solution.…
Light bullets in quadratic media with normal dispersion at the second harmonic
I. N. Towers, B. A. Malomed, F. W. Wise
Stable two- and three-dimensional spatiotemporal solitons (STSs) in second-harmonic-generating media are found in the case of normal dispersion at the second harmonic (SH). This re…
