Ultrafast Measurements Using a Silicon-Chip-Based Temporal Lens

摘要

Sample measurements of single iso-lated events on the sub-picosecondtime scale are of great interest for awide range of applications, includingnext-generation high-speed opticalcommunications, the observation ofextreme physical interactions and probesof chemical and biological processes.Current electronic oscilloscopes andphotodetectors are capable of single-shotmeasurements of waveforms with 30-psresolution. Several nonlinear opticaltechniques have also been developed tomeasure optical waveforms with few-femtosecond accuracy. However, theyhave been restricted to single-shot recordlengths of tens of picoseconds and havelimited update rates.
