Single-event effects (SEEs) refer to phenomena that arise from the interaction of single energetic particles with microelectronic devices, as is experienced in harsh radiation environments. Carrier generation induced by two-photon absorption (TPA) has become a valuable tool for SEE investigations of microelectronic structures owing to its unique ability to inject carriers through the wafer, directly into well-defined locations in complex circuits. Recent effort has focused on putting the TPA SEE technique on a more quantitative basis. This paper addresses the recent successes in achieving this goal, as well as the challenges that are faced moving forward.
Two numerical approaches for determining the charge generated in semiconductors via two-photon absorption (2PA) under conditions relevant for laser-based single-event effects (SEE) experiments are presented. The first approach uses a simple analytical expression incorporating a small number of experimental/material parameters while the second approach employs a comprehensive beam propagation method that accounts for all the complex nonlinear optical (NLO) interactions present. The impact of the excitation conditions, device geometry, and specific NLO interactions on the resulting collected charge in silicon devices is also discussed. These approaches can provide value to the radiation-effects community by predicting the impacts that varying experimental parameters will have on 2PA SEE measurements.
