Abstract
Conference Title: 2016 Progress in Electromagnetic Research Symposium (PIERS) Conference Start Date: 2016, Aug. 8 Conference End Date: 2016, Aug. 11 Conference Location: Shanghai, China There has been persistent exploration of new active materials and novel device architectures to dynamically control light with larger modulation depth and increased spectral range, at faster speed, and using less power. In this presentation, I will present experimental results showing that samarium nickelate (SmNiO 3 ), a prototypical phase-change perovskite nickelate, exhibits reversible large refractive index changes over an ultra-broad spectral range, from the visible to the long-wavelength mid-infrared (λ = 400 n–17 µm). The super broadband performance is due to strong electron correlation effects that allow extraordinarily large bandgap tuning of the order of 3 eV, and this new mechanism can be exploited to create active photonic devices.
