Systems and methods are provided for applying a protective graphene barrier to waveguides and using the protected waveguides in wellbore applications. A well monitoring system may comprise a waveguide comprising a graphene barrier, wherein the graphene barrier comprises at least one material selected from the group consisting of graphene, graphene oxide, and any combination thereof; a signal generator capable of generating a signal that travels through the waveguide; and a signal detector capable of detecting a signal that travels through the waveguide.
