WebJan 27, 2024 · Equation ( 7) shows that the complex Kerr angle has a non-trivial dependence both on the properties of the 2D material, encoded in its optical conductivity tensor, and on the dielectric constant of the substrate. In this work, we consider substrates with , which is in principle the most natural case in experiments.
WebThe following parameters were investigated: the spatial and temporal profiles of the laser pulses, the intensity of the exciting laser pulse, the length of the Kerr gate, the concentration of the sample solution, the relaxation time of the sample, the temperature, and the pair correlation factor. The optical Kerr effect has also been observed to dynamically alter the mode-coupling properties in multimode fiber, a technique that has potential applications for all-optical switching mechanisms, nanophotonic systems and low-dimensional photo-sensors devices. See more The Kerr effect, also called the quadratic electro-optic (QEO) effect, is a change in the refractive index of a material in response to an applied electric field. The Kerr effect is distinct from the Pockels effect in … See more The optical Kerr effect, or AC Kerr effect is the case in which the electric field is due to the light itself. This causes a variation in index of refraction which is proportional to the local irradiance of the light.
