  Up to this point streak-cameras have been a powerful tool for temporal
characterization of ultrafast light pulses even at the single photon level.
However, the low signal-to-noise ratio in the infrared range prevents
measurement on weak light sources in the telecom regime. We present an approach
to circumvent this problem. The method utilizes an up-conversion process in
periodically poled waveguides in Lithium Niobate. We convert single photons
from a parametric down-conversion source in order to reach the point of maximum
detection efficiency of commercially available streak-cameras. We explore
phase-matching configurations to investigate the up-conversion scheme in
real-world applications.
