This paper presents results of environmental tests performed on high frequency packaged, polarisation maintaining fibre-pigtailed Ti:LiNbO3 phase and Mach Zehnder intensity modulators. Most of the environmental tests carried out conform to the UK Defence Standard 07-55 and the test requirements specified by the European Space Agency (ESA) for components and equipment employed in space applications [1]. The modulators were subjected to vibration, shock and temperature cycling, to assess ruggedness of package and quality of fibre pigtailing technique. Stability of Ti:LiNbO3 devices in relation to pyroelectric and buffer layer drift is presented. Results of some preliminary work on the effect of moisture and outgassing of the epoxy used for fibre pigtailing are presented.
