Invertible optical nonlinearity in epsilon-near-zero materials
Epsilon-near-zero (ENZ) materials such as indium tin oxide (ITO) have recently emerged as a new platform to enhance optical nonlinearities. Here we report a theoretical and experimental study on the origin of nonlinearities in ITO films that are dominated by intraband and interband transitions. We s...
