Focusing light inside scattering media in a freely addressable fashion ischallenging, as the wavefront of the scattered light is highly disordered.Recently developed ultrasound-guided wavefront shaping methods are addressingthis challenge, albeit with relatively low modulation efficiency and resolutionlimitations. In this paper, we present a new technique, time-reversedultrasound microbubble encoded (TRUME) optical focusing, which is able to focuslight with improved efficiency and sub-ultrasound wavelength resolution. Thismethod ultrasonically destructs microbubbles, and measures the wavefront changeto compute and render a suitable time-reversed wavefront solution for focusing.We demonstrate that the TRUME technique can create an optical focus at the siteof bubble destruction with a size of ~2 microns. Due to the nonlinearpressure-to-destruction response, the TRUME technique can break the addressablefocus resolution barrier imposed by the ultrasound focus. We experimentallydemonstrate a 2-fold addressable focus resolution improvement in a microbubbleaggregate target.
