Abstract: A droplet optical resonator is a unique environment toinvestigate light–matter interaction and optomechanicsin liquids. Here, we report on light pressure effects derivedfrom whispering gallery modes excited in a liquid-polymerdroplet micro-resonator by free-space laser scattering. Fromthe nonlinear resonance spectrum observed in the visible, weprovide evidence of photon pressure exerted at the liquid-airboundary and quantify it with a coherent physical model.Our findings pave the way to studies on micro-rheology andnonlinear optofluidics, where droplets serve as miniatureliquid laboratories.© 2021
