Criteria for the experimental observation of multi-dimensional optical solitons in saturable media
Yi-Fan Chen, Kale Beckwitt, Frank W. Wise +1
Criteria for experimental observation of multi-dimensional optical solitons in media with saturable refractive nonlinearities are developed. The criteria are applied to actual mate…

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.…
