Abstract

Pulsed electron-induced responses observed in a proton exchanged LiNbO₃ optical directional coupler waveguide are presented. The proton exchanged coupler was observed to be less sensitive to electron radiation than a previously studied titanium indiffused LiNbO₃ directional coupler. A brief comparison of the attenuation and crosstalk behavior experienced by both couplers exposed to comparable electron doses is presented. The responses of the couplers are believed to depend on their respective photorefractivity and on the extent of radiation-induced heating.
