Adavncing materials. Improving the quality of life.
San Francisco (US), 2023, 10-14 April
Studies in epsilon near zero (ENZ) thin films have shown extreme nonlinear light-matter interactions leading to giant ultrafast nonlinearities. This corresponds to the excitation of ENZ modes and the associated electric field intensity enhancement (FIE) inside the material. Recent progress in the field mainly focuses on ENZ nonlinearity caused by electron absorption within the conduction band only, thus lacking an understanding of optical transition absorption near the ENZ regime. Therefore, an in-depth study of the nonlinearity, especially the nonlinear absorption behavior of the ENZ materials in the presence of optical transition, is crucial.
