Research output: Contribution to journalConference articlepeer-review


We have performed quantitative theoretical and experimental studies of all-optical self-induced polarization switching in thin films and waveguides of nematic liquid crystals, and demonstrated the feasibility of such processes over the entire visible-near infrared [0.4 - 1.55 μm] spectrum. We have also studied the detailed dynamics of the nonlinear optical interaction with the nematic crystalline axis, and observed interesting frequency selective beam amplification and stimulated scattering effects.
