a Illustration of the pump laser and layout of the microcavity. Parameters: \(a=170\) \({{{{{\rm{\mu }}}}}}\)m, \(r=50\) \({{{{{\rm{\mu }}}}}}\)m, \(s=0.15r\). b Temporal evolution of THz phonon polaritons in the microcavity. From left to right, are snapshots of the electric field of the THz phonon polaritons in the sample from t = 0 ps to 4 ps upon generation.
