We present a new class of clamped OMCs realizing — for the first time — optomechanical interactions in the resolved-sideband regime required for quantum transduction. We observe a record zero-point optomechanical coupling rate of g0/(2π)0.50 MHz along with a sevenfold improvement in the single-photon cooperativity of clamped OMCs.
