High-mobility transparent conducting oxides for compact epsilon-near-zero silicon integrated optical modulators

Wood, Michael G.; Campione, Salvatore; Serkland, Darwin K.; Parameswaran, Sivasubramanian P.; Ihlefeld, Jon; Luk, Ting S.; Wendt, J.R.; Geib, Kent M.; Keeler, Gordon A.

We study the role of carrier mobility in transparent conducting oxides integrated into epsilon-near-zero modulators. High-mobility materials including CdO enable sub-micron length electroabsorption modulators through >4dB/μm extinction ratios.
