Abstract
A method of encapsulating a phototransducer comprises mounting the phototransducer on a substrate, depositing a surfactant on the substrate, and depositing an encapsulant on the substrate over the surfactant. The surfactant alters a surface tension of the substrate. The encapsulant forms a protective structure that protects the phototransducer.
