High-mobility transparent conducting oxides for compact epsilon-near-zero silicon photonic phase modulators

Wood, Michael G.; Reines, Isak C.; Luk, Ting S.; Serkland, Darwin K.; Campione, Salvatore

We numerically analyze the role of carrier mobility in transparent conducting oxides in epsilon-near-zero phase modulators. High-mobility materials such as cadmium oxide enable compact photonic phase modulators with a modulation figure of merit >29 º/dB.
