Abstract

Efforts to examine large optical nonlinear response in structured and novel electromagnetic materials are ongoing. This work is partly motivated by the promise of leveraging structural resonances or regions of exotic materials response, such as the epsilon near zero or ENZ regime, to amplify the underlying nonlinear response of component materials. We explore the photo-induced change in optical properties under photoexcitation using pump-probe spectroscopy. The response shows characteristics wavelength and polarization dependent features that support the emergence of hyperbolic dispersion.
