1. An electroactive device formed by a process comprising the steps of:
forming one or more electroactive layers on a substrate, wherein the electroactive layers comprise a first conductive layer and a first electrode layer;
removing a portion of the one or more electroactive layers using a laser to define a gap in the one or more electroactive layers, wherein the gap is formed in a single step, wherein at least one of the one or more electroactive layers has a tapered sidewall; and
forming a second conductive layer and second electrode layer over the one or more electroactive layers and the gap, wherein the second conductive layer comprises a tapered sidewall formed by the laser and wherein the second electrode layer directly contacts either the first electrode layer or the first conductive layer, wherein the one or more electroactive layers is at least twice as thick as the second electrode layer, and wherein a width at a top of the gap is larger than a width at a bottom of the gap.
