Abstract
Tunable color pixels have a variety of applications from displays to photonic signal routing and sensing. Here we will present our recent simulations and experiments on tunable color pixels created from multilayer metal-hydride systems, showing vivid color production with wavelength shifts >100 nm during hydrogenation of various alloys. We show how pure metal hydrides can be used as tunable photonic elements throughout the visible and near-infrared, how alloying can lead to higher hydrogen fractions because of film stresses and microstructuring, and how novel optical materials can be used as substrates to further enhance these effects.
