Efficient on-chip Brillouin scattering on a tellurite-based photonic platform
On demand | Presented live 14 April 2026 
Abstract
We demonstrate on-chip stimulated Brillouin scattering on a monolithic tellurite (TeO2) based photonic platform through numerical simulation. Our simulation results show the confinement of both optical and acoustic modes within the waveguide, leading to enhanced opto-acoustic interaction, owing to the high photo-elastic coefficient of tellurite (p12 ∼ 0.241). As a result, Brillouin gain coefficients up to ∼ 190 W−1m−1 in a rib waveguide supported by silica substrate have been obtained.
