Preliminary radiation hardness testing of LiNbO/sub 3/:Ti optical directional coupler modulators operating at 810 nm

Integrated optics have the potential to replace conventional electronics in many instrumentation applications; in many cases the integrated-optics approach is the only one that will achieve the necessary bandwidth and information-density goals. Thus far, little work has been done to address the prompt hardness of these devices to intense ionizing-radiation fields. Preliminary data is presented on the response of optical directional coupler modulators (ODCMs) to radiation from a Febetron. The Febetron produces energetic electrons in the 300 to 700 keV range in approx.3-ns FWHM pulses, with a maximum dose rate of approx.1014 rad/s. The operation of the ODCM is monitored during and promptly after the Febetron pulse impinges the device. Long-term effects are also monitored. These data are analyzed with respect to the operation of such devices in a harsh, ionizing-radiation environment.
