Optical-field-induced current in dielectrics
WebI0 is the corresponding peak intensity of the optical pulse. Data from our model have been multiplied by the effective crosssection, Aeff , of the metal–dielectric interfaces confining the active volume of the dielectric (main text). - "Optical-field-induced current in dielectrics" WebWe report here electric-field-induced conductive pathway formation in a multiwalled carbon nanotube nematic liquid crystal blend. Experiments have performed by inserting the blend into a 10 µm planar, pre-aligned indium-tin-oxide coated sandwiched type electro-optical cell. The conductive pathway formation process have confirmed by in-situ porarized optical …

Weboptical pumping (or optical doping) creates holes and electrons simultaneously in the dielectrics, both of which could participate in inducing and carrying the current. In this Letter, we devise an asymmetric conduction to rectify the optical-field-induced current in dielectrics under the optical pumping by strong few-cycle laser pulses. WebPhysics of Classical Optical Processes in Dielectrics Concept: The interaction of the optical field with the bound or free electrons of optoelectronic materials by polarization or conduction allows to manipulate the light wave.
