Reconfigurable non-volatile silicon photonics using ultralow-loss phase-change chalcogenide Sb2Se3
Reconfigurable non-volatile silicon photonics using ultralow-loss phase-change chalcogenide Sb2Se3
Antimony Selenide (Sb2Se3) is explored as an alternative to popular phase-change materials (PCMs), such as Ge-Sb-Te (GST), for modulation of light through silicon photonic devices. Previous investigations of Sb2Se3 have been limited by using thin surface films, where only the evanescent field is modulated. By creating waveguide structures where light travels directly through the PCM, greater modulation depths are achieved, resulting in a higher change in effective refractive index. Applications of this work include light routing, photomodulation and photonic computing.

Abstract
Antimony Selenide (Sb2Se3) is explored as an alternative to popular phase-change materials (PCMs), such as Ge-Sb-Te (GST), for modulation of light through silicon photonic devices. Previous investigations of Sb2Se3 have been limited by using thin surface films, where only the evanescent field is modulated. By creating waveguide structures where light travels directly through the PCM, greater modulation depths are achieved, resulting in a higher change in effective refractive index. Applications of this work include light routing, photomodulation and photonic computing.
