Sonoluminescence is a well known laboratory phenomenon where an oscillatinggas bubble in the appropriate environment periodically emits a flash of lightin the visible frequency range. In this submission, we study the system in theframework of analog gravity. We model the oscillating bubble in terms of analoggeometry and propose a non-minimal coupling prescription of the electromagneticfield with the geometry. The geometry behaves as an analogous oscillating timedependent background in which repeated flux of photons are produced in a widefrequency range through parametric resonance from quantum vacuum. Due to ournumerical limitation, we could reach the frequency up to $\sim 10^5~\mbox{m}^{-1}$. However, we numerically fit the spectrum in a polynomial formincluding the observed frequency range around $\sim 10^7 ~\mbox{m}^{-1}$. Ourcurrent analysis seems to suggest that parametric resonance in analogbackground may play a fundamental role in explaining such phenomena in thequantum field theory framework.
