Three-Octave Supercontinuum Generation in Thick Crystalline Aluminum Nitride Waveguides
Samantha Sbarra, Samuele Brunetta, Pierre Arnaud Demongodin +4
We report an efficient extension of supercontinuum generation through dispersion engineering of crystalline aluminum nitride (AlN)-on-sapphire waveguides. Using a tailored epitaxia…

Sputtered AlN buffer layer for low-loss crystalline AlN-on-sapphire integrated photonics
Samuele Brunetta, Samantha Sbarra, Brandon Shuen Yi Loke +4
In recent years, aluminum nitride (AlN) has emerged as an attractive material for integrated photonics due to its low propagation losses, wide transparency window, and presence of…
