Ultrafast Optical Hydrogen Modulator in a Palladium Hydride Nanoparticulate Thin Film

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
An all‐optical palladium metal‐hydride modulator was investigated with ultrashort laser pulses, which can manipulate hydrogen positions on the femto‐to picosecond timescale. The incident photons activate interstitial hydrogen atoms and their subsequent trajectories affect the dielectric properties of the palladium hydride thin film, providing optical ...
