Design and modeling of subpicosecond all-optical modulator using the nonlinear response of indium tin oxide

We report the design of an all-optical modulator based on the ultrafast nonlinear optical response of indium tin oxide (ITO) combined with the sharp spectral features of a high-Q resonant grating structure. Under optical excitation, a thin layer of ITO exhibits an ultrafast, reversible, and large ...
