  Streak cameras are one of the most common and convenient devices to measure
pulsed emission e.g. from semiconductor lightsources with picosecond time
resolution. However, they are most sensitive in the visible range and possess
low or negligible efficiency in the infrared and telecom regime. In this work,
we present a frequency conversion based on sum-frequency generation that
converts infrared to visible signals while preserving their temporal
properties, making them detectable with a streak camera. We demonstrate and
verify the functionality of our device by converting the emission from a
quantum dot laser.
