Thermally induced all-optical inverter and dynamic hysteresis loops in graphene oxide dispersions Melle Hernández, Sonia Calderón, Oscar Gómez Egatz-Gómez, Ana Cabrera Granado, Eduardo Carreño Sánchez, Fernando Antón Revilla, Miguel Ángel We experimentally study the temporal dynamics of amplitude-modulated laser beams propagating through a water dispersion of graphene oxide sheets in a fiber-to-fiber U-bench. Nonlinear refraction induced in the sample by thermal effects leads to both phase reversing of the transmitted signals and dynamic hysteresis in the input- output power curves. A theoretical model including beam propagation and thermal lensing dynamics reproduces the experimental findings. © 2015 Optical Society of America. 2023-06-18T05:41:43Z 2023-06-18T05:41:43Z 2015-10-26 journal article 1559-128X 10.1364/AO.54.009143 https://hdl.handle.net/20.500.14352/23068 http://dx.doi.org/10.1364/AO.54.009143 eng FIS2013-41709-P GR/14-910133 restricted access The Optical Society Of America
