Giant optical nonlinearity in DNA lyotropic liquid crystals / L. Lucchetti, T.P. Fraccia, F. Ciciulla, F. Simoni, T. Bellini. - In: OPTICS EXPRESS. - ISSN 1094-4087. - 25:21(2017), pp. 25951-25959. [10.1364/OE.25.025951]
Abstract:
We report the experimental evidence of nonlinear optical response in DNA lyotropic nematic liquid crystals. Pump-probe experiments indicate that the non-linearity is remarkably large. Quantitative assessment of the non-linear optical coefficient by transient optical grating demonstrates that the response is of the same order of the well-known Giant Optical Nonlinearity (GON) of thermotropic nematics. These results represent a further incentive to the current investigation of potential applications of DNA in biophotonics.
