Abstract

We present the fabrication and characterization of an artificial crystal structure formed from a thin film of silicon that has a full phononic band gap for microwave X-band phonons and a two-dimensional pseudo-band gap for near-infrared photons. An engineered defect in the crystal structure is used to localize optical and mechanical resonances in the band gap of the planar crystal. Two-tone optical spectroscopy is used to characterize the cavity system, showing a large coupling (g_0/2π≈220  kHz) between the fundamental optical cavity resonance at ω_o/2π=195  THz and colocalized mechanical resonances at frequency ω_m/2π≈9.3  GHz.
