The ability of coupled waveguide devices to perform in adverse environments is of increasing concern for application in photonic systems. The intent of this paper is to examine the seemingly anomalous or nonlinear responses of two guided wave devices when exposed to the particular adverse condition of ionizing radiation consisting of protons and electrons. Physical models are presented explaining the different responses, and a possible method for partially controlling or mitigating these responses is discussed. The guided wave devices examined include: a polarization maintaining silica fiber and a titanium in-diffused lithium niobate channel waveguide directional coupler.
