The width of the depletion region in fused-silica samples thermally poled during various periods ... more The width of the depletion region in fused-silica samples thermally poled during various periods of time is investigated experimentally with four previously reported characterization techniques in an attempt to unify their findings. Although all measurements give a similar width of the depletion region, it is shown that the determination of the profile of ͑2͒ is also required for a good estimate of the nonlinearity induced by poling.
