Abstract

With this work we seek to cover a key space in the study of new materials for IR plasmonics: their integration on functional substrates. We show that Cd(Zn)O, a promising semiconductor oxide characterized by its low losses, can be grown in a polycrystalline form on a GaAs substrate. Despite this polycrystallinity, its plasmonic response can be described based on the physics of a homogeneous thin layer. With this study, we validate Cd(Zn)O for future integrated plasmonic systems on GaAsbased photonic devices.
