Recent demonstrations of single-crystal diamond cavity optomechanical devices [1] have made progress towards the realization of hybrid quantum technologies capable of controlling interactions between light, vibrations, and electron spins [2]. The microdisk structure studied here is advantageous due to the simple geometry, strong optomechanical coupling between high frequency mechanical resonances, and ability to support low loss optical modes [1]. We demonstrate optomechanically induced transparency (OMIT) in a single-crystal diamond microdisk fabricated from bulk diamond [1], an example of which is shown in Fig. 1(a). The device studied here exhibits dispersive optomechanical coupling between a TM-like optical whispering gallery mode with intrinsic quality factor of Q(i)o ~ 5 x 104 at λo ~ 1.5 μm and a 2.4 GHz frequency (ωm/2π) mechanical radial breathing mode (RBM), as shown in Fig. 1(b). The OMIT scheme, outlined in Fig. 1(a) requires coupling both a strong control (ωc), and weak probe field (ωp) to the cavity optical resonance (ωo). OMIT occurs when the control field is red-detuned from the cavity such that Δoc = ωo - ωc = ωm. When Δpc = ωp - ωc = ωm, a buildup of intracavity field photons is prevented, resulting in a transparency window in the probe transmission spectrum, and a dip in the probe reflection from the cavity [3].
