In this work, the authors numerically study the optomechanical properties of GaAs/AlAs based micropillar cavities confining light and acoustic phonons in the 18-100 GHz range. They evidence how the Poisson’s ratio and semiconductor/vacuum boundary conditions lead to distinct differences in the three-dimensional mechanical and optical confinement and derive ultra-large optomechanical coupling constants g0 in the 10^6 rad/s range.
