Abstract
Signal-processing systems based on linear time lenses are realized by
the combination of temporal quadratic phase modulation (which is a time lens)
and group-velocity dispersion. In practice, these systems suffer from aberrations
due to high-order phase-modulation terms in time lenses and aberrations due
to high-order dispersion in dispersive elements. We find that these two kinds
of aberrations can counterbalance each other under certain conditions. In
this paper we theoretically derive and numerically confirm the aberration-elimination
conditions for several time-lens based systems, i.e., temporal imaging, time-to-frequency
mapping and frequency-to-time mapping of optical pulse waveforms. In addition,
a frequency-time diagram is used to analyze the elimination process in order
to illustrate the physical mechanism.
