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