Abstract

Measurements of ultrafast optical waveforms using phase modulation (so-called time lens) have recently attracted considerable attention [1,2]. These methods allow one to achieve high resolutions up to 10 fs and to measure waveforms with temporal lengths up to 100 ps. However, nonideal lensing, the mismatch between a time lens and dispersions and higher-order dispersions lead to temporal aberrations of measured waveforms. Recently, a method of temporal superresolution based on periodic intensity modulation [3,4] has been proposed that does not require any dispersion and a specific shape of modulation. In this work, we propose the application of this method for measuring single-shot optical waveforms and numerically demonstrate its implementation.
