Traditionally, disorder present in optical systems introduces intolerable defects and negatively impacts performance through unwanted scattering. However, strategically implementing electric-field directed self-assembly methods to dynamically control disordered particle assemblies can be used to elicit favorable optical responses. Reconfigurable control over aspects of particle populations such as particle orientation, location, and number density enables tuning and enhancement of the optical response in a broad array of optical phenomena such as lensless imaging and random laser systems. Here we demonstrate the versatility and utility of exploiting disorder in our particle assemblies to control light scattering.
